Fantastic Automobile
by TXGP on 4/1/2026 9:49:47 PM
Have a 2020 M850I convertible. This car is amazing!!! Pure quality and luxury. Very fast when you want it, smooth running and shifting and fairly economical for this type of car. I have driven Mercedes Benz, Audi, Jaguar, and others. None can compare overall. I have taken this car on cross country vacations (top down in mountains, along beaches and on back country roads) and find it VERY comfortable. Road mileage at 24/25 mpg (happy with that). It is well built and sturdy with all the M-sport goodies. Depreciation is a bit of a negative, but that is the nature of any of this type of vehicle, but not excessive. Currently valued at 37% of MSRP after six years of enjoyment. Never a single problem, you just have to take good care of them. Mine is Sonic Racing Blue with black full Merino leather - beautiful. - 5.0
