need PPI in milwaukee

[jeff (moose)]

I am going to be buying an 85 500SEC (135K miles) from an individual in Milwaukee and need suggestions as what to look for and a good shop to do a though PPI for me.
I need someone well versed in euro cars and the 126 series cars and has some knowledge of how to spot strutual problems past and present.

I have always had W123's and 124's and this is my first 126.
I understand that the radiators are prone to breakoffage(sniglet) and the head gaskets seep oil. The front suspension has ball joint/ strut rod bushing problems.
I assume that what else do I need to be aware of when purchasing this vehicle?

thanks in advance
