The Mazda MX-5 sold in Japan as the Eunos Roadster from 1989 to 1997 is the first-generation NA, and it is the car that started the modern affordable roadster. Its light body and rear-wheel-drive balance make it one of the most driver-focused cars on the used market. The NA is also an easy car to live with, which is why so many are still on the road, but clean examples are now harder to find.
Most buyers want one of three things: a legal route to bring a Japanese-market Eunos Roadster or later MX-5 home, a fun weekend car, or a base for a track build. The NA and NB generations both suit those goals, and the import question depends on the build date.
NA or NB: which generation should you buy?
The NA (1989 to 1997 in Japan) is lighter and simpler, and many enthusiasts prefer its feel. The NB (1998 to 2005) is larger and heavier, with more power and a more refined cabin. The NB is the easier daily car, and the NA is the purist choice. Buy by condition first, since a rusty NA can cost more to restore than a clean NB costs to buy.
Japanese-market cars were rated under the voluntary industry cap, and rated output varies by engine and year. Use the factory sheet for the exact car, and do not rely on an advertised figure.
Is an NA or NB MX-5 legal to import to the United States?
Under the US 25-year exemption, a vehicle at least 25 years old can be imported without meeting federal safety standards, and the age runs from the date of manufacture. As of October 2026, every NA built from 1989 to 1997 passes the age test. NB cars built up to October 2001 also pass, and NBs built after that date do not yet qualify. The importer declares the car on Form HS-7 under Box 1, according to NHTSA's importation FAQ. That page does not show an effective or last-updated date, so confirm the build date before buying.
Emissions and state registration are separate questions, so check your state DMV before buying.
What could go wrong with an MX-5?
Rust is the main risk on the NA, especially in the rear arches, the sills, and the floor. Check the soft-top frame, the hood latch area, and the body mounts. A replacement soft top can cost a lot, so inspect its condition closely.
Check the engine for oil leaks and for signs of overheating. Ask about the cooling system, since overheating damages the head on older engines. Review the auction sheet grade guide if the car came through an auction, and confirm that the inspector's notes match the car.
Many MX-5s have been modified with suspension, exhaust, and engine changes. Ask for records of each change and check that the gearbox and differential are in good order.
Who should buy an MX-5?
Buy an NA if you want the lightest and most analog car and are willing to restore it over time. Buy an NB if you want a usable everyday roadster with more power. Either car rewards a driver who keeps the weight down and the tyres in good condition.

Frequently asked questions
Is the NA MX-5 a good first classic?
It can be, and it is cheap to run. Budget for rust repair and a soft top, since those costs are the most common surprises.
Can I import an NA MX-5 to the US now?
Yes on age, because every NA built from 1989 to 1997 passes the 25-year test as of October 2026. Confirm the build date and check state rules separately.
Is an NB MX-5 worth buying over an NA?
The NB is the easier daily car, but the NA is the lighter driving car. Choose by condition and how you plan to use the car.
What should I check on the soft top?
Look for tears, a warped frame, and worn hinges. Check that the latch and seals close without force.
