Prepurchase Inspection Mercedes mechanics in TX?
 

I'm looking at buying an AMG mercedes from a private seller in Waco, TX. The problem is that I am coming in from out of state and I want to find a mechanic in that area to do a pre-purchase inspection. Does anyone know a good mercedes mechanic in or around Waco Texas who could do this for me? I am looking to avoid taking it to a dealer for the pre-purchase inspection if possible as I've often had bad luck with mercedes dealer techs.

thanks!
