for $400-450 a month you could easily buy a used e90/92 (likely any model other than a 335) and not dump thousands of dollars into a lease you'll never get anything out of in the end.
I used to lease my cars but honestly its a waste of money in the long run. plus if things change you're not locked into the car.
