fyi- full Starmark info is referenced in the MBZ websites (dealer and corporate sites).
Not in Orange County, but.....recently purchased a Starmark 1994 E500 at 33,600 miles on it at Rusnak Pasadena,CA. It was my second Starmark purchase from Rusnak (and I reside in N Cal).
I reccomend Ed Keller- Internet Sales Manager. He provided great service and expertise (and is an 500e owner himself).
