Hi.

I am in need of a new car, as mine is shot, and I need a car that will be able to haul my harpsichord around to gigs. (I know. Get a hearse.)
I would like to do something more enviro-friendly than a gas car, and would rather opt for bio-diesel. I've been having a hard time finding diesel station-wagons that aren't either very old, or very new and extremely expensive. So any ideas there?

Also, I live in Wisconsin, and I have to park my car outside, so I'm a bit worried about how the car will start in sub-zero temps. Someone had told me that it's possible to get a warming kit of some sort that could remedy that. Does anyone know about this or other helpful ways to keep the vehicle functioning in the cold?

Your help is greatly appreciated. Thanks in advance.
