When my Model S is delivered I plan to stall electromagnetic sensors in the front and rear bumpers (see this thread: Found electromagnetic parking sensor system for front bumper) as well as a stealth radar detector and laser jammer. I've lined up a local shop to do the work, but I'm concerned (and the shop confirmed) that given that there will be no shop manual they'll have to wing it a bit. Does anyone know if the Service Centers will do this kind of work?
