How to Buy a 1985 Datsun/Nissan 720: A Practical Guide

Short introduction

If you’re looking to buy or value a 1985 Datsun/Nissan 720 pickup truck, here’s what matters: condition, rust, drivetrain (4x4 vs 2WD), cab style (King Cab vs standard), and originality. How to choose a classic Nissan 720? Focus on trucks under 100,000 miles with no frame rust—these typically range from $6,000 to $10,000. Over the past year, interest in clean, unmodified 1980s Japanese trucks has grown, especially among DIY owners who want reliability without complexity. If you’re a typical user, you don’t need to overthink this. Most well-maintained 720s are mechanically simple and easy to repair. The two most common distractions? Worrying about minor trim differences or chasing ‘rare’ badges—neither significantly affect daily use or long-term ownership cost. The real constraint? Rust. A seemingly solid truck can hide structural corrosion in the bed, cab corners, or frame rails. That’s what kills value—and safety.

About Datsun Pickup Trucks

The Datsun 720 was produced from 1980 to 1986 as the successor to the 620 series. By 1985, the Datsun brand had largely transitioned to Nissan in most markets, though many still refer to these trucks as 'Datsun' out of habit. Mechanically, the 720 is known for its ruggedness, rear-wheel-drive layout, and available four-wheel drive system. It offered both regular cab and extended King Cab configurations, with inline-four and inline-six engine options. The 1985 model year sits at the end of the 720’s production run, meaning it includes refinements like improved interiors and more reliable electrical systems compared to earlier versions. These trucks were designed for utility—light hauling, farm work, off-road use—and not luxury. Their appeal today lies in mechanical transparency: parts are simple, repairs are doable with basic tools, and modifications are straightforward. If you’re a typical user, you don’t need to overthink this. What you see is usually what you get.

Why the 1985 Nissan 720 Is Gaining Popularity

Lately, the 1985 Nissan 720 has seen renewed attention in enthusiast circles. This isn’t driven by performance or prestige—it’s about practicality in an era of increasingly complex vehicles. Modern trucks come with advanced electronics, driver aids, and high repair costs. In contrast, the 720 offers analog driving, predictable handling, and minimal reliance on computers. Recently, younger buyers entering the used truck market have begun favoring older Japanese imports that avoid the rust-prone steel and finicky fuel injection of American counterparts. The 720 fits this niche perfectly. Additionally, social media and online forums have made it easier to find parts, share restoration tips, and locate trustworthy sellers. Communities on Reddit 1 and Facebook groups 2 regularly feature restored 720s, often highlighting their trail capability and low-cost maintenance. This visibility reinforces demand. But popularity doesn’t mean all examples are good buys. Condition varies wildly. That’s where judgment—not nostalgia—matters most.

Types and variants

The 1985 Nissan 720 came in several configurations, each suited to different needs. Understanding the trade-offs helps narrow your search.

Variant Pros Cons
2WD Regular Cab Lighter weight, better fuel economy, lower purchase price Limited passenger space, less resale appeal, fewer features
2WD King Cab Extra seating/storage, more comfortable interior, easier to resell Slightly higher cost, added weight reduces efficiency
4x4 Regular Cab Off-road capable, durable transfer case, simpler than later SUVs Tight rear space, harder to find with low miles
4x4 King Cab Best balance of utility and comfort, highest collector interest Premium pricing, more complex maintenance (driveshafts, hubs)

If you’re a typical user, you don’t need to overthink this. For most people, the 4x4 King Cab offers the best long-term value. It’s versatile enough for weekend trails and daily driving. However, if budget is tight and you only need occasional hauling, a 2WD Regular Cab can be a smart starting point. Just expect limited appeal down the line.

Key features and specifications to evaluate

When assessing a 1985 Nissan 720, focus on five core areas:

  • Engine type: Most 1985 models came with the Z20S (2.0L) or Z24 (2.4L) four-cylinder, or the L20B (2.0L) six-cylinder. The Z24 is the most desirable due to torque and parts availability.
  • Mileage: Under 100,000 miles is ideal. Under 50,000 commands a significant premium, especially if documented.
  • Rust level: Check frame rails, cab mounts, bed floor, and wheel wells. Surface rust is manageable; structural corrosion is a dealbreaker.
  • Transmission: 5-speed manual is preferred. Automatics exist but are less reliable and less sought after.
  • Originality: Unmodified interiors, factory paint, and matching numbers increase value for collectors—but not necessarily usability.

When it’s worth caring about: If you plan to resell or show the truck, originality matters. When you don’t need to overthink it: If you’re buying to use, drive, and modify, prioritize function over form. A repainted truck with fresh brakes and tires is often a better daily driver than a showroom-perfect one with seized joints.

How to buy a 1985 Nissan 720

Follow this step-by-step checklist to avoid costly mistakes.

Step-by-step checklist

  1. Set a budget ($4,000–$10,000 covers most usable examples).
  2. Determine primary use (daily driver, project, off-roader).
  3. Search listings on Bring a Trailer 3, ClassicCars.com 4, and Facebook Marketplace.
  4. Filter by location (avoid long-distance purchases unless verified).
  5. Inspect in person—or hire a mechanic if buying remotely.
  6. Test drive: Listen for transmission knocks, check 4x4 engagement, verify steering alignment.
  7. Review service history and ownership records.
  8. Negotiate based on needed repairs (tires, brakes, exhaust, etc.).

Decision flow

  • If you want reliability → Choose a well-documented 4x4 King Cab under 100k miles.
  • If you're on a tight budget → Consider a 2WD Regular Cab needing cosmetic work.
  • If you plan to modify → Prioritize solid metal over appearance—customization hides flaws.
  • If you want collector potential → Look for low-mileage, original-paint, unmolested examples.

Recommendations by scenario

  • First-time owner: Aim for a $6,000–$8,000 King Cab 4x4 with recent maintenance.
  • DIY builder: Find a rust-free shell under $5,000 and upgrade gradually.
  • Weekend driver: Target a clean 2WD model with modern tires and brakes.

Red flags / what to avoid

  • Frame rust—especially near rear axle mounts or cab corners.
  • Rebuilt title or salvage history without full documentation.
  • Engine overheating signs (cracked heads were common on early Z24s).
  • Vinyl roof or excessive aftermarket mods—often indicate neglected maintenance.
  • Pricing significantly above market average without justification.

If you’re a typical user, you don’t need to overthink this. Most problems are visible during a 30-minute inspection. Trust your eyes and ears more than the seller’s story.

Price & market insights

The value of a 1985 Nissan 720 varies widely. According to recent sales data, prices may vary by region/model/seller. As of late 2023:

  • Fair/Project Condition: $3,000–$5,000 — running but needs work.
  • Good Driver Condition: $6,000–$10,000 — clean, maintained, minor wear.
  • Excellent/Show Quality: $10,000–$18,000+ — low-mileage, restored, or rare trims.

The CLASSIC.COM Market Benchmark (CMB) listed the average value of a 1985 Datsun 720 at $10,796 5. However, this reflects top-tier examples. Most private sales fall below that. Factors like rust-free body, 4x4, King Cab, and original interior boost value. Enthusiasts pay extra for trucks with service records and low ownership count. To verify current pricing, check completed auctions on Bring a Trailer or aggregated data on Classic.com 6.

Top-seller & competitive analysis

While the 720 stands on its own merits, it competes indirectly with other 1980s compact trucks like the Toyota Hilux (RN30/RN40), Ford Ranger (first gen), and Mazda B2000. The table below compares key aspects:

Model Reliability Rust Resistance Parts Availability Market Demand
Nissan 720 High Low–Medium High Medium
Toyota Hilux Very High Medium Very High High
Ford Ranger Medium Low Medium Low
Mazda B2000 High Low Medium Low–Medium

The 720 holds up well in reliability and parts access but lags behind the Hilux in long-term demand. Its advantage? Lower entry price and growing cult status among budget-focused off-roaders.

Customer feedback synthesis

Based on owner reports from forums and auction reviews:

Common praises:
• "Simple to fix—I replaced the clutch myself in a weekend."
• "Gets me through snow just fine with all-terrain tires."
• "Fuel economy surprises people—regular gas and 23 mpg highway."
Common complaints:
• "Door seals leak in rain—common issue on older models."
• "Steering feels vague at highway speeds—needs alignment every year."
• "Finding OEM bed parts is nearly impossible now."

If you’re a typical user, you don’t need to overthink this. Most issues are manageable with routine upkeep. The truck won’t impress neighbors, but it will get the job done.

Sourcing & supplier tips

Where to look:

  • Bring a Trailer: Best for transparent auction histories and detailed photos.
  • ClassicCars.com: Aggregates dealer and private listings nationwide.
  • Facebook Groups: Active communities like 'Datsun 720 Owners' offer local deals and advice.
  • eBay Motors Blog 7: Occasionally highlights featured builds and sourcing tips.

Tip: Always request a VIN check to confirm accident history. Use services like NICB or provider-specific tools. Avoid shipping without a pre-purchase inspection. Verify return policy if buying from a commercial seller.

Maintenance, safety & legal considerations

Maintenance is straightforward but requires vigilance. Key items:

  • Timing belt: Replace every 60,000 miles (interference engine risk).
  • Brake fluid: Flush annually—moisture buildup causes soft pedal.
  • Bearings and seals: Front hubs and rear differential need periodic repacking.

Safety-wise, the 720 lacks modern crash protection. Drive defensively, especially at night or in heavy traffic. For legal compliance, ensure working lights, seat belts, and emissions (if required in your state). Confirm local regulations before registering a modified vehicle. Modifications affecting structure or lighting must meet minimum standards—check with your DMV.

Conclusion

If you need a simple, repairable truck for light duty or weekend adventures, choose a rust-free 1985 Nissan 720 with a 5-speed manual and 4x4. If you're seeking a low-cost first project, a 2WD model under $5,000 makes sense. If you want long-term appreciation, focus on originality and low miles. If you’re a typical user, you don’t need to overthink this. Function beats flair every time.

Everything You Need to Know

What is a 1985 Nissan 720 worth today?

Most 1985 Nissan 720s sell between $4,000 and $10,000 depending on condition. Well-maintained 4x4 King Cabs with under 100,000 miles often reach $8,000–$12,000. Project trucks can be found under $5,000. Prices may vary by region/model/seller. For accurate valuation, review recent completed sales on Bring a Trailer or Classic.com.

Is the Datsun 720 the same as the Nissan 720?

Yes. Datsun was Nissan's export brand until the early 1980s. The 1985 model was sold as a Nissan in most markets, though it shares the Datsun 720 platform and design. Mechanically, they are identical. The name difference reflects branding, not engineering.

Yes, many mechanical parts (clutches, brakes, suspension components) are still manufactured or available used. Some trim and body panels are scarce. Check specialty suppliers like Grafton Auto Gallery 8 or online forums for hard-to-find items. Aftermarket support remains strong for engines and axles.

Does a 1985 Nissan 720 have 4x4?

Some models do. The 4x4 version was optional and features a manual transfer case. It’s more desirable than 2WD due to off-road capability and higher resale value. Confirm drivetrain type by checking the gear shift pattern and presence of front differential.

How reliable is the 1985 Nissan 720?

Very reliable when maintained. The Z24 engine and 5-speed transmission are durable. Common issues include rust, aging rubber seals, and electrical gremlins. With basic upkeep, these trucks can last decades. If you’re a typical user, you don’t need to overthink this—just stay ahead of wear items.
