I currently own an '06 Insight for commuting to work. Not fun to drive in the usual sense, but fun to see what kind of hyper-mileage I can get. During the summer it's easy to top 70 mpg, more of a challenge in the winter (usually 62 - 65mpg).
My weekend car is a '97 Miata M-Edition. Great on winding mountain roads getting to climbing rides. I have a receiver and a 1-bike rack on the back. Very dependable and does everything (sports car wise) better than my '67 MG Midget (which had tons of retro-coolativity . . . and not much else).
My dream car: Lancia Stratos.
