I bought a 1997 Pontiac Firebird Trans Am late in 1996.  It came with t-tops, chrome wheels, 6 speed manual transmission, leather seats, and the Monsoon stereo.  I've done a few things to it but I bought a fast car so I wouldn't have to modify it much.  I've added a MAC STB (strut tower brace), relocated the IAT sensor (intake air temp.), disabled CAGS (the skip-shift thing) and put in synthetic fluids in the engine, transmission, and differential.  I've also added minor things like chrome lug nuts (those plastic black caps are ugly!) and PIAA 959 fog lights because one of the stock ones broke and the dealer wanted too much money for a replacement.  I made my own cold air intake with some 4" intake hose and a big 9" conical K&N filter.  I also added a Decoma cat-back exhaust system with some nice tips on the ends.  In the future I'd like to add subframe connectors and short throw shifter.  Oh yeah, I also added a bunch of stereo equipment I had leftover from my previous car (a 1991 Ford Escort GT).
