It's all depends on the shop. Current shop alignment techniques can actually make a car straighter than it was when it left the factory. I've personally experienced this on one occasion and have seen a friends car go through far more than you're describing and he still owns the car 8 years later. I'll tell you this though, odds are you'll be bringing it back for supplemental repairs for the next couple of months. I had a few minor issues after mine was in the shop for 8 weeks. Finally got the bugs worked out and had 4 trouble free years with it until I traded it in.
