Very simple process. My truck had been in the shop 5 times. Document EVERYTHING (dates, names, repairs, statements made by anyone who works for the dealership or GM). I had a 4 page report i sent to the attorney. If you arrange some deal with the dealership regarding a buyback, you can be assured you're getting screwed somehow. Contact www.lemonlaw.com, the process took approximately 3 1/2 months.
