I think (right now) I'd probably be a Ford Crown Victoria. Rugged, dependable, keeps on going no matter what crap gets thrown at it...
Why do you think the Crown Vic is used as a police cruiser / taxi in so many areas?
As for my daily driver, it's a 2006 Dodge Charger R/T with the Hemi. Big enough for long drives, with enough horsepower for fun.
