No doubt about it, the 645ci is a head turner and a joy to drive - when it is working. There lies the problem. Under warranty, the various reliability issues I experienced concerning the roof, seat sensors and manual transmission were simply taken care of with a service visit. Since rolling off my warranty late last year, I've been paying $500 to $1000 every 1-2 months to fix the same chronic issues. Either BMW can't fix them or they don't stay fixed and I have found both scenarios unacceptable for a luxury, performance automobile.
Bottom line, choose wisely and either extend the warranty, have the service manager marry into your family, or pick up a glossy of the 645ci for your wall and buy drive something else.
P.S. It may be a good marriage, I happen to know the BMW service department makes good money at least off me every month or so.
