2002 M6 GTO, less than a week old. Bugged me because I got a slight pull to the left and my steering wheel was possibly 2 degrees off center to the right during normal straight line driving. I probably wouldn't have even noticed in a car not designed for performance driving but the level of feedback this car gives made it more irritating. I took it in and I'm glad I did. I requested to see before and after and it was farther off up front from the factory than any car I have ever owned. I don't remember the exact specs and he wouldn't let me have a copy for whatever reason but it was pretty well out of range on the camber and the total toe up front. They got it pegged nearly dead center and got the steering wheel straight for me. Just pulling out of the dealer's parking lot at low speed I could tell things had changed but it didn't become obvious until I had some speed up and also took some turns. It felt probably 15% better to drive, at least to me. The turn in now seems more confident and concise to me when before it seemed to be undecided right at initial turn in. The car tracks straight on the highway now and also seems less jittery. It is clearly a noticeable difference. I have read about one other GTO being off from the factory alignment wise so if you suspect something can be wrong up there then be sure to get it checked. It's a long boat ride over with lots of loading and unloading from trucks, much room for some slight impact alignment changes. Plus, Holden isn't exactly familiar with transporting vehicles this way and they may not have the experience yet to align left hand drive vehicles for American roads. I honestly have no idea, just speculating possible scenarios... Or I could just have got a fluke where the guy who set it up was going to lunch or something as soon as he was done. The dealer did not charge me, they were great about it. Just a simple and hopefully unnecessary warning. Take care.
