Gosh, I've driven vehicles that I considered "fun" for various reasons. My dad's F150 4x4 was real fun with big off-road tires and a lift kit. Went all over the place off-roading, and even going up sand dunes. My Mustang GT was fun in a "too young, too much horsepower" way. ()

My wife's 2011 WRX is fun because it accelerates like crazy, and handles like a go-kart.
That's interesting. What made your Contour SVT fun? FWIW I had a 1998 Contour SVT. While I really liked that vehicle, its fun factor for me has been eclipsed a few times over.
