Just wanted to pass this along as we all think about keeping our cars clean during the winter months. I've tried to do winter car washes on my own in the past and the motivation seems to dwindle as the temps approach freezing around here... Autowashes are risky in general. I've been using a mobile detailer, Curtis (C & C Auto Detailing), for a few years and now w/ my Model S. He has the usual credentials (clients w/ Ferraris, Lambos; local sports figures, etc) and has done an excellent job on my cars. Recently, he did an exterior detail using C-Quartz Finest on my Model S -- and charged me $150 (he showed me the bottle) -- so I really don't think he has a huge markup. Anyway, I wanted to get some group pricing (5 or more cars) going for at least monthly hand washes as follows: exterior = $25, int/exterior = $40. I'll ask for even lower pricing if the group grows to 10 or more. Of course he can do all the other detailing necessary (eg individual exterior is $125) anytime of year. He is mobile so will drive to you (assuming DC area) and brings his own water supply. Looking at his website, these are massive discounts on his regular prices. Please let me know if any of you are interested -- btw, I'm not getting anything other than the group pricing for posting this. Thanks, guys.
