As you all know I am planning on buying a M3 soon. As I have read in several post, I should have a compression test run and a cooling system pressure test run.

Does anyone know what the compression should be at for a 97 and a 95 M3 with 60-80k on it?
Also where should the pressure test be at for the cooling system.

I am just wondering what to look for when the mechanic comes back and tells me numbers that normal wouldn't make sense to me.

If any of you guys have had one of these two test run lately, can you tell how much it cost and what I should be looking to pay on a average. If anyone knows of a trust worth shop or dealership in north chicago, that would help alot. Thanks MadBMW
