2nd on the VW TDI!! I recently got 58mpg on my 01 Beetle TDI 5spd but understand that the Golf & Jetta can get even better! I just picked up a 1997 Passat TDI 5spd for $1200 and got 45mpg not even trying and it's bigger than your Accord AND the range per tank is 800+ miles! I'm not knocking the Honda's I've had 10 of them and loved every one! But when my 95 Toyota Avalon with a 3.0L v6 got better mpg than my 1993 Accord EX 4cyl, I was shocked and opened my mind to a whole new concept. Now Ecomodder has my mind racing!! I WANT 50mpg+ and won't stop till I get it consistantly!!
Good luck with your hunt!!
p.s. My 01 Beetle will be for sale $5000 if you're interested
