I wrecked my E36 m3 and most of it got repainted, I am getting back from the body shop on Friday...

Q1: What should I look for as far paint quality. And what type of leverage do I have if I don't think it looks good?

Q2: How do I care for the new paint. Please list the steps in as much detail as possible, with suggestions of products/tools.

1. The body shop should guarantee your satisfaction.

2. Do nothing except wash it for the first month (maybe two?) while the paint cures. After that period, you can wax it, etc. You should get a care 'guide' from the autobody shop on exactly how long to wait for this.
