Vehicle inspection - west mids area

[CSLchappie]

I'm looking to buy another E60/1 M5 but from a private seller. I have a car in mind but I'd like to get it inspected prior to purchase just to confirm all mechanicals are okay, verify service schedule, check for error codes etc.

I've spoken with Sytner Oldbury but they can't/won't help, does anyone know of any other places in the west midlands where I could get this done, ideally someone who knows a bit about these cars.
