From what I understand that 308 is expensive to maintain. Your going to find owning the NSX refreshing because all your going to be replacing is clutches and tires. It is a shame that you are only now attempting to aquire that car and didn't have it a few months ago. We just had the NSXPO in New York. It is a track event where you really get to find out what your NSX will do. ( if you do not know how to handle your car on the track someone will teach you ). The NSXPO is out west this year (Arizona ).
Price: It is all but impossible to find this car under $27,000. It is very rare to find one under $30,000 most of what you are looking of is between $30,000 and $35,000. The upshot is that most NSX'es have low miles.....To give you an Idea I bought a '98 with 6000 miles for $45,000 ( I looked for a yellow one for 3 years) You are lucky, there are more Red NSX'es than any other color.
The thing to worry about in the first two years of production is a snap ring in the transmission (manual) if it has not been replaced it is a bit of a costly fix. There is also a small issue with the electric windows. If you buy a '93 or newer you will not have the trans issue, it you buy a '95 or new you will not have any issues. if you buy a '96 or newer you get a 6 speed instead of the 5 speed ( 6 speed cheaper to repair ) The '97 also had the optional Targa roof (its cool, I have one). Major body change in 2000. At any rate, anything you could possibly want to know about the car is on
