That's a good car, decent price. Some things to consider/ask owner:
*He might say it doesn't leak oil, but it may or may not burn it. The 1ZZ for this generation is pretty notorious for burning oil. Sometimes you get lucky and can find a gem. Other times you have to constantly add oil or rebuild the engine with bigger oil return holes on the pistons.
*I don't think that spoiler is OEM, you should double check the seals, make sure it doesn't leak.
*Looks like there is no tach. Either get some sort of scangauge or similar (you should do that anyway) or swap in a newer gauge cluster from another Corolla (like my 2001).
*Check for rust, it is Mighigan after all!
I'm not trying to scare you out of this car, it is a good car with good FE. Just want to help you do your homework, before you pull the trigger.
Good luck!
