High-End Body and Paint Work Needed

Have a late model M3 that was sideswiped. Want to get it back to new condition. Trying to find a shop that does great work. I've had two cars done by Stuttgart and I'd say that they came out 95-98%. I want 100% for this car. Anyone know of a craftsman who does high-level body and paint work? Anyone have experience with the body shop at the BMW dealer in Denver? Thanks much.
