hey looking at possibly buying a 90 sc. it looks real good. looked like it was sitting for a while, but the guy started it and everything, ran smooth, started right up. First time in an sc, and wow they are quick, and they smoke tire I was wondering, is there anything i should check that you wouldnt normally check before buying a car? other thing is gas. what kind of mpg do they get, and do they take regular or do they need premium. thanks!
