a new 4ag can be had for about 100$ at cofers. for that same price he can get a nicer redtop 4ag thats higher comp. making it an even better autox car.

also my 2nd supra had 244k miles when the odo broke and i still autoxed it, and it ran well.

depending on the condition of the car $900 may be a good price, if it was well keeped, looks clean, no aparent wrecks ide get it. but ive seen many 1st gen mr2's for a lot less that need little work to become a nice car.
