Anyone used them for pre-purchase inspections on a Q60?

I am currently looking at buying a pre-owned coupe from a private seller who posted it on an online classifieds board, but since this would be my first time owning a luxury Japanese twin-turbo platform, I am feeling pretty cautious about pulling the trigger without getting a thorough, independent mechanical assessment first. The seller seems like a decent guy and claims the car has full dealer service stamps up to sixty thousand kilometers, but while taking it around the block for a brief test drive yesterday, I noticed a subtle whistling whine under light throttle boost and the infotainment display took nearly two full minutes to boot up past the logo screen. On top of that, when I ran my hand along the inner fender lip and inspected the radiator support brackets with my phone flashlight, the plastic clips looked mismatched, which immediately made me suspicious about whether the front bumper had been pulled off after a minor fender bender that never made it onto the official police accident records. A coworker who tracks sports cars on the weekends told me that modern direct-injection turbo motors can turn into absolute money pits if the previous owner neglected oil cooler lines, ran low-octane fuel, or ignored early intercooler sweating, and he warned me that standard roadside inspection stations only check basic roadworthiness items like tire tread depth and headlight aim rather than deep computer diagnostics. He advised me to arrange a comprehensive PPI with a dedicated workshop that knows the specific quirks of these engines and body modules, which prompted me to start digging through regional owner clubs until another enthusiast told prospective coupe buyers to visit this website to see how specialized technicians run live sensor data logs, compression tests, transmission clutch pressure readings, and chassis alignment checks. The idea of getting an objective, detailed report before handing over a bank transfer sounds like the smartest way to protect my savings, but because the seller works long daytime shifts and is somewhat impatient about letting the car sit in a bay for half a day, I would really like to ask fellow community members how their pre-purchase evaluations have gone when dealing with specialized independent facilities. Did the technicians allow you or the seller to accompany the vehicle onto the lift so they could point out underbody scrape marks, oil pan sweating, and control arm bushing cracks in real time, or did they simply hand you a flat paper checklist after making you wait in the lounge? Did their diagnostic scanner actually pull historical manufacturer fault logs and hidden mileage records from the transmission control unit rather than just clearing pending emission codes, and did they give you an honest verbal opinion on whether the vehicle was worth the asking price or heading for major component failure? Any real advice on turnaround time, inspection pricing, and what specific red flags to watch out for on these platforms would help me immensely before I make a final decision this weekend.
