I feel like you are both parked backwards. Sweet ride!

it’s a good two to choose from for sure. They will have similar power. The age factor of the f80, and the cost of maintenance of the M. I remember my M car costing more to maintain. I like the styling better on the f80. I’d choose the M340i to daily.

Do M340i get charged M oil prices at the dealer?

Agreed, no curved screen. I’m a fan of analog cluster also. F30 analog cluster 8.8" screen.
