I've been searching for a 2017 M4 for months and finally found one that ticks all the boxes, but I'm nervous because I've heard about crank hub issues and rod bearing failures on the S55 engine. Before I hand over any cash, I really want to get a proper BMW Pre Purchase Inspection Dubai done by someone who knows these performance cars inside out. I need a mechanic who'll do a compression test, scan for overrevs and hidden fault codes, check the charge cooler for leaks, and put it on a lift to look for any suspension damage or accident repair. Has anyone here used an independent inspector they'd recommend for an M car? I don't mind paying extra for a thorough report, I just want to avoid buying a car that's been tracked without proper maintenance. Any recommendations would be hugely appreciated.
