NikG,
I have driven the 02 Spec V, I LOVE that car. Sure some people have complaints about it, but they, as said above, are isolated. Not every car has that. For 2003, They have re-done the transmission, with better gearing ratios, and such. As far as I know, no 2003 Models have that nasty first-year-teething oil consumption problem. The spec V is the best bang for the buck, you're getting, essentially what the old (4th generation Max was) 4DSC - or Four-door sports car. The car handles very well, and BEGS you to drive it, and hard at that. If there are any problems, your manufacturers warranty will cover it.
About buying used...I bought my 97 GXE used, and NEVER again will I buy used. The problem being is that you dont know what kind of moron owned the car before you did, if they babied it, or drove it like a total maniac, and really could care less. I think that is what happened with my car...the previous owner beat the hell out of it, and I have had some problems with it, but thats another story.
Best of luck, and let us know what you decide on!
