So I had to chime in with info about the Vibe. ;)
8 months ownership
18K miles on odometer
0 (zero, none, nada) issues.
30mpg. From day 1 to day 241. We have driven on hills, in the city, on the highway, with A/C on and off, and I commute 680 (Fremont to Walnut Creek) at 70+mph every weekday. It always gets ~30mpg.
Oil changes and tightening the Parking Brake (after I ran a few miles with it on. Oops) is the only work that has been done on it.
Hmmm, need a car icon too....
