Leased on 535i with 6 spd, premium, sports and cod weather package. Took off the run flats and am storing them until the end of the lease. This is the 2nd BMW I have followed this ritual. Car handles like it is on rails. Performance is sooo sweet. Previously had a 530i with manual. The extra ponies - 45 or so are noticeable and the torque comes on just above idle at 1400 and stays flat until about redline. I commute about 45 miles to work and this beemer makes going to work fun! Have had beemers since 2000 and they are the utmost fun to drive but run flats stink big time. BMW- please hear this = run flats belong on a Lexus for those who don't want to change a tire in the rain.
Smooooooth and yet powerful engine, silky smooth trans and clutch.
Get rid of run flats. Change the exterior styling back to 2003 classic design or at least get rid of the flame headlights. Think about hiring the 2009 Audi A4 designers!
