The Honda NSX (NA1, 1990 to 1996 in Japan, with the NA2 following in 1997 to 2005) was the first all-aluminium production supercar from a mainstream maker, and the first generation is the car to buy if you want the original chassis. Its 3.0-litre V6 with VTEC revs freely and sounds distinctive. The NA1 is also more affordable than many rivals, but clean examples now sell for far more than a decade ago, so an inspection matters.
Buyers usually want one of three things: a legal route to bring a Japanese-market NSX home, an analog driver, or a collector car. The NA1 works for all three, but the import question depends on build date, and that is where many buyers go wrong.
NA1 or NA2: which NSX should you buy?
The NA1 is the original 3.0-litre car, and the NA2 (1997 to 2005) is the later 3.2-litre version with updated suspension and a more refined cabin. Many enthusiasts prefer the NA1 for its lighter feel and simpler layout. The NA2 is the easier daily car.
Japanese-market cars were rated under the voluntary industry cap. Rated output differs by year and specification, so compare the factory spec for the exact car rather than relying on an advertised figure.
How do the NSX generations compare?
- NA1: built 1990 to 1996 as the original 3.0-litre car, with the C30A V6 and VTEC. It has the lighter feel many enthusiasts prefer, and it suits a collector or an owner who wants the original chassis.
- NA2: built 1997 to 2005 with the 3.2-litre C32B V6, revised suspension, and a more refined cabin. It is the easier car to use every day.
The build years are the usual split between the two generations. Mid-cycle changes blur the line, so confirm the year and engine from the chassis plate and export paperwork for the specific car.
Is an NSX 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 is counted from the date of manufacture. As of October 2026, NSX cars built up to October 2001 meet the age test, which covers the NA1 and the early NA2 cars. Cars 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. Check your state DMV and, in California, CARB rules before you buy.
What could go wrong with an NSX?
The NSX has a reputation for reliability, but age and neglect cause problems. Check the timing belt service history, because a belt that is overdue is a serious risk on the C30A and C32B engines. Look for oil leaks, coolant leaks, and worn suspension bushings.
Many NSX owners in Japan and abroad have had cars with replaced parts that do not match the original. Ask for records that name the parts and dates, and check the chassis number against the registration. Read the auction sheet grade guide to understand what inspector notes mean if the car came through an auction.
Rust is less of a problem on aluminium bodies, but the steel subframes and suspension mounts still corrode. Check the rear floor and the mounts closely.
Who should buy an NSX?
Buy an NSX if you want a mid-engined car with a lightweight chassis and can pay for careful upkeep. The NA2 is the better choice for regular driving, and the NA1 suits a collector or an enthusiast who wants the original feel.

Frequently asked questions
Is the NSX a reliable car?
It can be, when the timing belt and cooling system are kept up. Service history matters more than the odometer.
Can I import an NSX to the US now?
As of October 2026, NSX cars built up to October 2001 meet the 25-year age test. Confirm the build date from the chassis plate or export paperwork.
Which NSX should I buy first?
Buy the NA2 if you plan to drive the car often. Buy the NA1 if you want the original chassis and accept higher upkeep.
Is the NSX expensive to maintain?
Routine service is costly because parts and specialist labour are expensive. Budget for the timing belt, fluids, and suspension work in the first year.
