How to Buy a 1970 Datsun 510: A Practical Guide

Short introduction

Lately, more buyers are turning to the 1970 Datsun 510 as a driver-friendly classic that balances affordability, simplicity, and driving engagement. If you’re asking how much is a 1970 Datsun 510 worth? or what to look for in a Datsun hatchback from 1970, here’s the quick verdict: expect to pay between $13,500 and $28,000, depending on condition, restoration quality, and originality. A clean, rust-free sedan in good mechanical shape is worth prioritizing over show-ready builds unless you plan to display it. The most common mistake? Overvaluing minor trim differences while ignoring structural integrity. If you’re a typical user, you don’t need to overthink this. Focus on drivetrain health, body condition, and verifiable history—not whether it has factory hubcaps.

This piece isn’t for keyword collectors. It’s for people who will actually use the product.

A well-preserved Datsun 510 hatchback—rarity affects value, but usability matters more for daily drivers

About the 1970 Datsun 510

The 1970 Datsun 510, known internally as the PL510, was part of Nissan’s push into global markets with a compact, front-engine, rear-wheel-drive sedan that emphasized handling and reliability. Sold under the Datsun brand in North America, it featured independent suspension, a 1.6L inline-four engine (L16), and earned praise for its responsive dynamics—earning nicknames like “the poor man’s BMW.” While primarily offered as a four-door sedan, it also came in two-door and five-door wagon forms. A true hatchback variant wasn’t officially sold in the U.S., though some European and Canadian markets received fastback-style bodies that resemble hatchbacks.

Its reputation grew post-production, especially among grassroots motorsports enthusiasts. The 510 became a favorite in amateur road racing and rallying due to its lightweight frame and tuning potential. Over the past year, interest has increased not because of celebrity ownership or auction hype, but because practical classics are getting harder to find. If you’re a typical user, you don’t need to overthink this: the 510 stands out for usability, not rarity alone.

Why the 1970 Datsun 510 is gaining popularity

Recently, there's been a quiet shift in collector behavior. Buyers aren't just chasing six-figure restorations—they want cars they can drive without anxiety. The 1970 Datsun 510 fits perfectly. Unlike fragile exotics or high-strung performance machines, the 510 was built to last. Its mechanical simplicity means parts are easier to source, repairs are less costly, and breakdowns are rarely catastrophic.

Another factor: fuel prices and supply chain issues have made modern car ownership less predictable. In contrast, the 510 runs on regular gasoline, uses common tools for maintenance, and doesn’t rely on software updates. This reliability—combined with genuine driving enjoyment—has drawn new attention. Forums report rising search volume for 'daily-driven classics,' and the 510 consistently ranks high in usability surveys1.

When it’s worth caring about: if you want a vintage car you can actually drive weekly. When you don’t need to overthink it: if your goal is pure investment speculation—there are flashier assets with higher short-term returns.

Types and variants

The 1970 Datsun 510 came in several configurations, each suited to different priorities:

Four-Door Sedan: Most common version. Offers practicality and better preservation odds due to original family-car status.
Two-Door Sedan: Slightly sportier appearance, rarer, often modified. Higher demand among enthusiasts.
Five-Door Wagon (Estate): Excellent cargo space, cult following in rally circles. Prone to rust due to lower production numbers.
Fastback/Hatchback (non-U.S.): Marketed in Canada and Europe. Often mistaken for a true hatchback. Limited availability today.

Variant	Pros	Cons
Four-Door Sedan	Widely available, easier to maintain, stable value	Less visually distinctive, fewer performance mods
Two-Door Sedan	Sportier look, enthusiast appeal, higher resale	More likely to be over-modified, harder to insure
Wagon	Unique, functional, strong community support	Rust-prone, limited parts, niche market
Fastback (Hatchback Style)	Styling edge, rare outside Japan/Canada	Hard to verify authenticity, import complications

If you’re a typical user, you don’t need to overthink this: choose the sedan unless you have a specific need for cargo or styling. Rarity doesn’t equal usability.

Key features and specifications to evaluate

When assessing a 1970 Datsun 510, focus on these core areas:

Engine (L16): Should idle smoothly and pull without knocking. Look for signs of overheating or oil leaks.
Transmission: Four-speed manual standard; five-speed swaps are common. Check for grinding or slippage.
Body Condition: Rust around wheel wells, floor pans, and rocker panels is the top killer. Use a magnet to check for bondo patches.
Suspension & Brakes: Original design used MacPherson struts and disc brakes up front. Ensure no excessive play or fluid loss.
Interior: Vinyl seats and analog gauges. Faded dashboards are common; cracked ones suggest UV damage or poor storage.
Provenance: Service records, ownership history, and matching numbers add value—but only if credible.

When it’s worth caring about: if planning long-distance drives or resale. When you don’t need to overthink it: if buying as a project car already missing most components.

Pros and cons

Pros:
- Simple mechanics = lower repair costs
- Engaging driving experience
- Strong aftermarket support
- Fuel-efficient by vintage standards (~25 mpg)
- Compact size makes city driving easy
Cons:
- Prone to rust in snowy climates
- Parts availability varies by region
- Minimal sound insulation
- No airbags or ABS
- Insurance can be costly without usage restrictions

How to buy a 1970 Datsun 510

Beyond knowing how much a 1970 Datsun 510 is worth, you need a process. Here’s a step-by-step guide:

Checklist before purchase

Verify title status (clean vs salvage)
Inspect for structural rust (especially under carpets and fenders)
Start the engine cold—listen for knocks or smoke
Test all gears and clutch engagement
Review service history—if none exists, assume worst-case wear
Get a pre-purchase inspection (PPI) from a specialist
Confirm VIN matches documentation

Decision flow

If budget < $10k → consider project cars only
If budget $13k–$20k → aim for mechanically sound, cosmetically fair examples
If budget > $25k → target fully restored or documented low-mileage models
If location has road salt → avoid any model without full undercoating history

Recommendations by scenario

Daily driver: Prioritize mechanical freshness over paint quality
Weekend cruiser: Balance aesthetics and function—look for recent brake/suspension work
Investment: Focus on originality, low mileage, and SSS trims
Track use: Accept non-factory upgrades (roll cage, cooling mods)

Red flags / what to avoid

VIN mismatch or missing plates
Rebuilt title without full disclosure
Excessive interior modifications (may hide water damage)
Photos taken in dark garages or at odd angles
Seller refuses PPI or test drive
Priced significantly below market average

If you’re a typical user, you don’t need to overthink this. A transparent seller with maintenance receipts beats a glossy ad every time.

Price & market insights

As of early 2025, the average sale price for a 1970 Datsun 510 ranges from $13,500 to $28,000. Hagerty Valuation Tools list a #3 (“Good”) condition example at around $17,600, while pristine (#1) models have sold at auction for over $57,0002. However, values may vary by region/model/seller—especially in coastal states where rust is less prevalent.

Recent trends show steady demand without speculative spikes. Unlike some Japanese classics (e.g., Supra, Skyline), the 510 hasn’t been inflated by pop culture. That stability benefits buyers seeking usable vehicles rather than flipping assets. When it’s worth caring about: if comparing multiple listings across platforms. When you don’t need to overthink it: if you’ve found a solid car within your budget—even if it’s slightly above average.

Top-seller & competitive analysis

Platforms like Bring a Trailer (BaT) and Classic.com offer real-time insight into active sales. Over the past year, completed auctions reveal consistent pricing patterns:

Platform	Avg. Sale Price	Time on Market	Buyer Notes
Bring a Trailer	$22,000–$26,000	7–14 days	High trust in photos and video walkarounds
Classic.com Listings	$18,000–$24,000	Variable (often >30 days)	More private-party negotiations
eBay Motors	$12,000–$20,000	15+ days	Higher risk of undisclosed issues

Competitors in the vintage compact segment include the Toyota Corolla Levin and Mazda RX-2, but neither offers the same blend of handling balance and serviceability. The 510 remains distinct for its BMW-inspired engineering ethos.

Customer feedback synthesis

Analysis of owner forums and post-purchase reviews reveals recurring themes:

Positive:
- “It feels alive when you drive it—no numb steering”
- “Fixed my own head gasket with basic tools”
- “Gets compliments everywhere, even from non-car people”
Negative:
- “Floor rotted out after one winter in New York”
- “Spent more on rust repair than I paid for the car”
- “Hard to find OEM-style trim locally”

The biggest regret? Skipping a professional inspection to save money. If you’re a typical user, you don’t need to overthink this: invest in verification upfront.

Sourcing & supplier tips

Original parts are scarce, but reproduction components are widely available through specialty suppliers. Recommended sources include:

Z Car Warehouse: Offers L-series engine gaskets, suspension kits
Datsun Motorsports: High-quality brake lines and bushings
510Registry.org: Community marketplace for used OEM parts

For international shipping (e.g., fastback models from Canada), ensure customs paperwork is complete. Verify compliance with emissions and safety standards in your state or country. May vary by region/model/seller—always check local requirements before import.

Maintenance, safety & legal considerations

Maintaining a 1970 Datsun 510 requires routine vigilance:

Change oil every 3,000 miles or annually
Inspect brakes and suspension biannually
Store indoors or under breathable cover
Treat undercarriage annually with rust inhibitor

Safety-wise, the 510 lacks modern aids like ABS or crumple zones. Drive defensively, especially at night or in wet conditions. Consider adding seatbelt upgrades or LED lighting for visibility.

Legally, registration depends on your jurisdiction. Some areas classify it as a historic vehicle after 25 years, allowing reduced fees or emissions exemptions. Confirm eligibility through your DMV or transport authority. This piece isn’t for keyword collectors. It’s for people who will actually use the product.

Conclusion

If you need a vintage car you can drive regularly without constant worry, the 1970 Datsun 510 is a compelling choice. Choose a rust-free sedan with documented maintenance if you want reliability. Opt for a restored SSS model only if you value collectibility over utility. If you’re a typical user, you don’t need to overthink this: prioritize condition over cosmetics, and drive it often.

Everything You Need to Know

How much is a 1970 Datsun 510 worth in 2025?

Between $13,500 and $28,000, depending on condition, mileage, and originality. Fully restored or low-mileage models may exceed $50,000 at auction. Values may vary by region/model/seller.

Is the Datsun 510 reliable for daily driving?

Yes, if properly maintained. Its simple mechanics make repairs manageable, but rust resistance depends heavily on climate. In snowy regions, underbody protection is essential.

Are parts still available for the 1970 Datsun 510?

Yes, many mechanical and cosmetic parts are reproduced. NOS (New Old Stock) items appear occasionally online. Joining owner clubs improves access to rare components.

What’s the difference between a Datsun 510 and a ‘hatchback’ model?

The U.S. never got an official hatchback. Some overseas markets received fastback-style bodies that resemble hatchbacks. True rear access requires lifting the trunk lid, not a top-hinged door.

Should I buy a project car or a turnkey model?

Choose a turnkey car if you want to drive immediately. Project cars often cost more in labor and parts than anticipated. Only pursue restoration if you have time, skills, or a trusted shop.
