Where can I get an affordable BMW inspection in Dubai?

[keatonketteridge]

I'm looking at a used 2016 BMW 3 Series and the seller is asking a fair price but I'm on a tight budget and can't afford to get ripped off. I know I should get it checked but every place I've called wants way more than I expected. Is there such a thing as an affordable BMW car inspection before you buy that doesn't compromise on quality? I'm not looking for a cheap shortcut, just something reasonable. The car has about 90k km and the guy says it's clean but I've heard too many stories about hidden accident damage and turbo issues. Any recommendations for someone who won't charge an arm and a leg? Also how do you handle it if the seller refuses to let the car be inspected? That would be a red flag for me.
