You can find someone to take over your lease.
And for anyone else that wants to test-drive the M-coupe but isn't planning to walk out of the dealer with one the same day,
DON'T TEST-DRIVE THE M-COUPE. Heck, you have a 3.0si; I have a Z4M-roadster, and even I couldn't stop thinking about the M coupe after test-driving it.
Don't make the same mistake I did.
The M-roadster and M-coupe are 2 completely different animals.
