Used 2009 Pontiac G6 GT Convertible for Sale near Kitchener, ON

We initially had problems with the factory tires (shaking the car). Ditched the Goodyears ASAP after dealing with dealership, Goodyear and GM squabbling over who would replace these POS expensive tires. Eventual dealership replaced two tires and Goodyear replaced the other two, after numerous tire rotations and huge amounts of tire balancing lead. We switched to a cheap no-name brand from Discount Tire and never had another issue with the car shaking and vibration so bad you could not see out of the rearview mirrors. Headlights failing due to plugs melting. This was eventually solved by replacing all sockets with replacement parts from auto supply store. We did not use GM replacement harness that was hugely over priced. I filed a NTSB complaint on the headlights as both beams failed while my wife was driving 70 mph at night. This scared her so much she will not drive it at night. About a year after warranty expired, brakes failed. Towed car to dealership where it sat for a month having the ABS system replaced (big $$). Drove off with car and brakes failed. We did not make it home. Another week at dealership having break lines bleed. Third try and brakes failed again - brake pedal was mushy to the floor and required pumping to get the car to stop. Towed car to private mechanic who replaced an inexpensive *cough* master cylinder and we have not had anymore brake issues. Retractable hardtop has worked fine since day-one, but the car has had a rattle in the roof that the dealership never resolved. There are some things I really like about the G-6 and some things that make me feel like I bought an over-priced lemon. On a sunny day driving with the roof down I can almost forgive Pontiac for the many flaws in this car - almost, then I put up the roof and hear that danged rattle.
