Hey man so sorry to hear of your nightmare with this shop. It's always risky when you go to get these things done, as you've learned. It seems as if you didn;t even really NEED this done just looking to maximize/maintain your X to the fullest and got burned. Hope you get them at least refinished and as the guys said to have them properly address the pulling and vibration. I'd lead heavily with this complaint then move on to the wheel damage. This way their on the defensive already. What a pain and with you uncle working there too can possibly complicate things more than help.

Anyway, I've also seen great wheel repair done at the dealer with a third party coming in. Whoever services DCH BMW in Freehold NJ does an awesome job. I saw a set of E46 as well at 911 wheels redone and they looked flawless. His skill set even advanced and he now offer repair to E46 M3 wheels which have that "hyperchrome" finish (not really sure what it's called but it's sort of like chrome but not?!?!?!?!). I think he got around $100 per wheel.

Good luck and regardless your X5 kicks ass.
