Yup!

I had a 2018 650i GranCoupe (AWD) in Carbon Black and upgraded to a 2019 M6 Gran Coupe in San Marino Blue.

1) I don't remember feeding engine oil outside of regular maintenance on my M6 in the last 30,000KM, whereas I've constantly had to top up in the 650 every 5-7K KM

2) 650 is gonna be very comfy, though with the runflats on the 650 versus Michelin PSS, the M6 felt less bumpy if you can believe it lol; but putting the suspension setting in sport plus will change that

3) M6 gas mileage is better for whatever reason, that's what I noticed

4) I have the M Perf Titanium exhaust on my M6 and its LOUD, coldstarts are deafening, especially in a garage, underground parking, etc...

I loved both but the M6 wins in looks and perceived engine reliability

I do not drive it hard until engines are warm, and usually let it cool down a bit by driving conservatively home before shutting it off and still got two bottles of oil in the trunk for rainy days. No issues so far, knock on wood, going to do the 55point inspection that the dealer offers for cheap this up coming service interval.

Oh one more thing, M-Tax is real, everything is pricier :/

Final opinion, if you're not getting the 650 for its AWD, I'd get M6
