I have contemplated getting another GLI....great fun, great fuel econemy, and a beautiful car. An MKIV TDI also sounds good w/ chip, and all the crap I was reading about on clubTDI.com, there are a few videos on you tube of guys in TDIs walkin gassers...very impressive...and 40+ mpg. The only thing is how high will diesel fuel go, at $5 a gallon and gas at $3.00, its still a break even w/ 30-40% improved fuel economy....did I mention torque?!
