People are selling them all the time on www.b15sentra.net , and they're often already modded. I would definately reccomend 03 or newer, becuase the 02s had crappy engine internals, and the gear ratios were kind of whack. They fixed all of that in 03. BUT, in 04, they switched to the plain-looking front end. Check it out:

02-03 front end:


04+ front end:


I just used yellow cause I found those pics really fast. Mine is black, and if I had to do it over again, I'd probably get silver (VERY easy to keep clean). But black looks sick.

The only other major revision was in 04 they went to a wideband 02 sensor and slightly better tuning. So they average around 5whp more. Personally, I'd look for an 03. They're VERY cheap right now, look the best, and don't have any internal engine issues liek the 02s did. PM if you want any more info (or if you wanna know what kind of mods can do what, etc).
