I just traded in my 2003 Cavalier for a 2009 cobalt. I really enjoyed driving it and had no real issue in the 160000 km. Rotors warped by 20k and again at 40000. Replaced with inexpensive after market brand and never had another problem. Wheel hubs were done while car still under warranty.I did very little maintenance, oil changes every 10-15 k, nothing else the owners manual suggested. It always started even in - 30 Celcius -22F. I got over 800km on a tank several times,38US mpg 6.1 l/100. I never really took good care of it and in 6 years it never let me down. I was impressed by the acceleration, 0- 100 km in 8.5 seconds is not bad for a car that cost 13 grand tax in.
fuel economy, reliability ,performance
put brake rotors on the car that are at least as good as a cheap aftermarket set
