2008 smart fortwo pure 2dr Hatchback (1.0L 3cyl 5AM)
I find that I get over 40 MPG I have 24,000 miles on the car now and love it. It parks anywhere and I haven't had a lick of trouble with it. The car is amazingly stable on the highway and has plenty of space for two and a weekends worth of gear and supplies. I love it and would buy another one.
gas mileage, drivability, built in safety features. amazingly fun.
I thought about this for a long time and these trivial things are really all i could come up with. The transmission software could be refined sometimes it has a mind of its own, also the sound system could be better, and the brakes pads are very dusty.
