Reviewed a 2005 BMW 645Ci Convertible RWD on Feb 13, 2012
I love the way it drives. It's powerful and has excellent road manners both on the highway and around town. I had forgotten just how much fun BMWs are to drive. It's very different from the 500CL that I replaced; sportier. It's unlike my 911; softer. It's nothing like my Ferrari; quieter. Initially I had a difficult time getting used to the I-Drive system. Once I mastered it, it got better. It's still complicated to make some minor adjustments but it's not as terrible as many say. I'll never understand why manufacturers went to run-flat tires. This car would ride and handle even better without run-flats. I'd install them but there's no room for a spare tire. It's simply a great value for your automotive dollar.

I like everything about the car. They are sleek and top of the line. A bit spendy on repairs but best drive on road and fun at the beach. I would recommend for those who want a special treat. Thanks
