ehhh both have good and bad... but both can be pretty fun cars... out of the two I am not really sure which one I would pick. However if its the specific cars pictured above... I would probably take the S2 but that is based upon first glance and the fact that the Z has a nasty color Interior imo, however it would also depend on how they felt when I am driving them, if the S2k or Z felt like crap...I obviously wouldnt want it either.
As for imports=cheap metal crap... ehhh if its cheap metal crap.... cheap metal holds up pretty well in a bad accident then. I wouldn't exactly call them cheap metal crap, some of these cheap metal crap are really reliable. Its a matter of opinion. I love my Integra to death and wouldn't trade if for the world but I would also pick up an Audi given the chance. Trust me...you want to talk about car's falling apart American and European car's are no better (Yes I have experience with All 3 Jap (I know my teggy inside and out) and korean imports, Audi - Euro and American: ford and chevy. I also worked for an Audi dealership porting and test driving as well as fixing some of the minor problems that you didn't need a lift to do.) Every car has it's fault's... it's all a matter of opinion and what you like to drive. You dont have to like other car's as long as you like what you drive. Don't worry about what other people like and if they like something different there shouldnt be anything wrong with that, they are the ones driving it, not you. Thats just my .02.
