Time has finally come for us to part with the Z4. It's an '05, with about 28K miles on it, 6 speed manual. We bought the car in 2009 with 3800 miles on it. Most of the miles have been put on it by my wife, and most are local, not highway miles. I added the Aero side skirts, and the front Aero bumper, as well as the rear spoiler. I swapped the wheels for Bremmer Kraft wheels, and Michelin PS2 tires about 7-8K miles ago. This is also the car that I did the custom sound system install in, Alpine head unit and amp, Hertz speakers, and a 10" sub in the trunk in a Custom built enclosure that doesn't intrude on the trunk space. The car runs out great, has been well maintained, looks good for an 11 year old car. There are a couple of parking lot dings, 2 minor ones that I know of. I've set the price as a starting point to see what the market is like, I'm wiling to consider reasonable offers, and will get more pics up soon.
