Sooooo, 2673 - 2354 = 319 lbs lighter, but that is not taking into account the difference in weight of the engines. The Saturn engine is an aluminum block, so it's gotta be lighter. The dude says that he thinks the VW engine weighs about 290 lbs. Finally, I think the Saturn wagon (the dude's future/final car target) weighs more than 2354 lbs.
Wow, considering the only four door TDI available was the Jetta,...
Four door TDI In the US/Canada:
1996~97 Passat (B4)
1997~99.5 Jetta (A3)
1999~present Jetta (A4, A5)
2000~2005 Golf (A4)
2001~2005? Passat (B5.5)
Touareg (if that beast counts as a 'four-door') to present
There were also reportedly three B5 Passat (1998) and two A3 Golf (not known if 2 or 4 door) brought in, but like the Loch Ness monster and Sasquatch, these have not had benefit of irrefutable photographic evidence.
