i would get an old merc like the old one i had, but in better shape, and i'd go for the 6 cylinder model, and i'd do it in a heartbeat.
Ideally this
Collectabile Mercedes Benz
or this
1967 Mercedes Benz
I loves baby blue! But ya, i want to buy one again someday regardless. It's kinda either soup up the mr2, or get one of those as a second car, when i have more money that is...
