My 2017 F80 competition is ending it's lease contract soon and I wanted to ask opinions on next steps.

MSRP was $85,000 and residual is at 62% (contract price $52,700).
36 mo lease, 10k mi per year, $1025/mo with $0 down.

I'm at month 32 with 22k miles and the dealership is appraising my car at $48,000. However KBB lists it at $55k private seller and the same dealership is selling a black version of the same car, same mileage for $55k as well.

Considering the amount of money I spent on the car (added CF mods, ceramic coat, spacers) should I buy this car out or turn it in for something else?

IF I turn it in, I'm looking for something a little less stiff as the roads and drivers here are atrocious. I've been looking at the Z4 M40i and the leasing payment are a bit less than my M3. Also considering an M2 Competition but I feel like the stiffness would also be an issue for me. Thoughts? TIA!
