I'm pretty nuts about keeping my cars clean, but I can't even get my SL looking that nice and its only driven 2k a year.
Mine are nice drivers, those are museum pieces.
The only 2 I've seen even close to the same as the ones listed in JGS are Patrick (Mbeige) and Derek (Turbobenz) during my trip to Cali.
Poor picture, but its the 2 behind mine.
