I've had it since August. 4000 miles already. Close to hibernation time though.
My dealer got an unexpected allocation in June so I traded in my 2022 Z4 M40i and ordered the G83. Two GREAT improvements over the Z4. Next to nothing for back draft with the top down and the same for side wind turbulence with the windows down. Talking 60 MPH on anything but freeways, which is 90% of our road mileage.
