+1 for Marc/Jacob and the AutoLavish Crew.
I've had them work on 6 of my BMW's over the past few years and I'm continually impressed with the absolutely awesome job they do. I've worked with many detailers in the past before I was introduced to Marc through a coworker of mine (the Yellow NSX featured on their site), and none of the other detailers came even remotely close to the quality of the work Marc and the AutoLavish team have done with my cars. If you are looking for the best high-end detailer, look no where else!
They did a 40+ hour wet sand job on my Jerez Black '08 E92 M3 in late 2010, they've detailed my '02 M Coupe and lately my '12 335is last week - ALL done impeccably.
