| you can go check out brabus in newport if you are a fan of merc.
but, to be honest there are really not a whole lot of tuners down in the OC.
Racing Dynamics is down here in san clemente, but they don't have a show room i believe.
CEC is up in los angeles. you can check out SVC (Special Vehicle Concepts) and the ferrari dealership off of PCH in newport too. SVC specializes in suv's though.
most place are up in la. like 310 motoring, west coast customs, and tons of other "baller shops"
