there's actualy a 2002, 2002.5, 2003 and 2003.5, all are actually distinctly different, (well 2002.5is prettymuch the same as a 2003 but it's pretty minor stuff. DIff cupholders, (02's are covered, 02.5+'s actualyl work) 02's and 03's have diff rims (02's are swept-style, 03's ar ekinda chunky) the sub and no rack thing was the addition for the 03.5 also 02's autos are normal and 03's are tiptronic style.
Ether way, the only advice I'd have in lookng for one isto get a stick, even if you don't know hw to drive one, jsut get one and learn. it makes all the difference int hese cars. sems to be a common grievance "wish I'da got a stick" If you do that, get a shortshifter (I recommend B&M), though as the stock shifter's like driving a damn schoolbus or something. YOU have to throw shifts like you're throwing punches. (sometimes at your big gulp which gets messy) There's also a ton of inexpensive or no cost thigns you can do like trimming your doorlocks, etc.
Anyways, welcome, where you from? This place is a great resource, let me jsut recommend that before asking alot of questions, give a search a quick spin 'cause ppl here get grouchy about that, and realistically the majority of stuff's been covered pretty thouroughly at one time or another. I for one don't care as much, and everyone;ll usually give you a break if you're a noob besides it's alot of crapto filter through.
