Hey, count me in on the VW bandwagon. I can't believe they are the only manufacturer who sells a decent diesel engine in a passenger car. I have a Jetta Wagon TDI, which gets 50mpg. I regularly get 500 miles on a single fill-up.

*and* when I am using pure biodiesel, it gets 250mpg in terms of greenhouse gas emissions (B100 is 20% fossil fuel based).
In terms of sound quality, the stock speakers in the 2003 Jetta are pretty good, with really fantastic bass. A great foundation for aftermaket systems, and you'll need it because the stock sound in *awful*. But a new headunit fixes that up really nice... I used an Alpine because I liked the ergonomics. But if you replace the head unit, then you'll have to modify the FM antenna cable from the HU, or else reception will suck. It takes five bucks worth of parts from Mouser. (Hey, I just got back on topic for this thread )

What's cool, is that Chrysler is releasing some TDI's in the next year. Finally an American car company that is doing the right thing for the environment. Fuel cells are at least 10 years away from being a reality in cars, even though everyone says it is the "next big thing" and will "save the world". In the meantime, we'll keep burning fossil fuels like merry fools for another decade. Do your research on global warming, and you learn that this is something that we can not afford to do.
Oops, OT again... time for a time out
