[UKjohnnycobra]

I imported my Cobra from the UK. Importing the vehicle is subject to federal not state laws. The federal requirements vary, depending on the year of manufacture of the vehicle. I believe that a 30 yr old vehicle will not be subject to federal EPA compliance and so you should be able to import the complete car. You will need DOT approved wheels tyres and glass. Once in the US it then has to comply with the laws of the state which is issuing the registration which may be different to the feds.
In my case, because the car was built in 2002 it would have been subject to federal emissions and other high level safety standards (ABS, anyone?), so I sold the engine and gearbox in the UK, shipped the car as an "incomplete vehicle assembly" and sourced a new drive train in the US. I got lucky as NY has an "emission compliant" status for custom cars ( as it was eventually registered). I did not know this ahead of time. Also, FYI the car was never inspected when it was imported, it was all self documented, but the penalties are high if they catch you doing something bad.

The EPA has a section somewhere on its website for importing vehicles. I advise you to understand the state requirements before you ship, as you could end up paying the ship a car which the state will disallow. Hope this helps.
