I'm looking for someone around the Commerce Twp/Farmington Hills, Michigan Area that would be willing to look at a car I'm about ready to purchase. I'd feel much better if someone from these forums was able to give it a once over. Please email me at ddavis95@gmail.com if you can.

Also, has any one heard of Motorwerks Group? Is it a good shop to have a compression and leak down test done?

I called Erhard BMW Of Farmington Hills and they quoted me $500!!!! For a once over, compression test, and leak down test.

Sounds about right for the checks. They charge $200 just for the inspection. Never heard of motorwerks group. I live over in Clinton Township. I have the compression and leakdown gauges, but have never done it on the M3, only to my race car(s).
