I'm not sure about any one else, but I've had a terrible time getting parts for my GXP. I've purchased various trim items (granted this probably isn't very common), all the way to normal wear and tear items.
So far out of 15 to 20 items I've purchased, all but one has come from Lansing MI.
Today I was looking for front brake parts since I'm putting new pads (Ceramix) and rotors on the front. I wanted a brake hardware kit and nobody can supply one aftermarket made for the GXP. Worse yet, the only way it is available from GM is with the pads. Even when I checked on pads, they told me they would be coming from the US.
I've checked all the common places such as NAPA, Part Source, Canadian Tire, Auto Value, etc. I've had the same information from everyone.
Starting to get really frustrated
