What are your experiences as an M3 lessee?

I am considering the M3 premium RWD atm. At the current lease deal, it just seems like the way to go if I want to try a Tesla and especially try FSD. Leasing and buying one after (if I want) is probably cheaper than financing, or I can just ditch it and try something else entirely.

One of the things that has me pausing is how anal they are going to be when I return the car. I know mileage overage is 0.25/mile, but more concerned about small cosmetic stuff, scrapes, scratches, etc. The person at the dealership said I would get a packet outlining this, but apparently only after I actually start the lease. So asking around, what have your experiences been like leasing from Tesla? Any unexpected gotchas?
