I drive a full-size van because...
1.) Buying it off my parents was hell of a lot cheaper than buying something used elsewhere.
2.) Never having to worry about sub enclosure size. Ever. Actually, I've never had to worry about fitting anything in...'fridges, couches, mattresses, six, eight, ten of my friends, 10 foot pieces of pipe, Christmas trees, a riding lawn mower...
3.) Full size air bed > any car's backseat. 'Nuff said.
4.) It's solid metal, unlike most cars these days. Provides an excellent RF ground for my radio gear. Also, if I ever get into a wreck with it, those real metal bumpers are going to be worth it...
The next vehicle I get will most likely be a smaller truck - just for the utility of it, and to get something I could drive out on the beach with. Preferably something diesel, so I could make my own fuel and not have to worry about silly gas prices //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
