Definitely something dealerships wouldn't allow on a test drive.
Why go to a BMW dealership when there's an actual BMW M festival? There really shouldn't be any debate here. Rarely (if ever) will dealers allow prospective buyers take the cars out to a lot to do donuts. That's why there's such a thing called an M Festival. So what happens at an event like this? Lots of tire smoke. And drifting. And yes, donuts. Check out the video ahead and watch the new M3 and M4 blow a blaze of smoke as they dance around an open lot.
No matter how much you beg, a BMW sales rep won't let you try this on a typical test drive. Then again, just slip them a few bucks. You never know.
