From my past experiences of shoppng for a 2nd gen, things I'd look for: Engine Compression check, timing belt change, accessories changed (water pump, oil pump, etc.), run through the gears and check for grinding (is it a 97 tranny too?), and also if it is a 3sgte swap I'd check to see if he/she did a good job and took their time with the swap. Since you are new to MR2s, it'd probably be good to find a friend that knows more about them to take along with you. If it is a 97 Engine, you'll have a CT20B turbo, which I also have on my personal car. Lots of fun
