First and foremost...
I want a 1961 Big, Black, Caddillac Station Wagon. I have wanted on ever since I can remember. My original want was to go around picking up hitch-hikers with it and telling them they need to sit in the back. Of course, that fantasy also involved a cassette of funeral music, a skeleton dressed in a tux, a coffin with a creaky lid and the use of hydraulics to liven things up a bit.
My next choice, only because I love Gravedigger with a passion is a 1950 Chevy pannelled truck.
After that... it's pretty much any fast car that can outrun speeding tickets and stay on at least 2 wheels going around corners.
