I can't recommend these guys enough! They do a GREAT job and are very reasonably priced for the level of service they provide. I used to go to the larger franchises with the pretty gift shops, but a friend recommended I give California Auto Detailers a try. I was VERY pleased.
They do get very busy because they detail many of the local auto dealerships cars, but if you have to wait a few days to get an appointment, it's worth it.
If you have a larger vehicle, like an SUV, or your car is heavily soiled, they'll charge a bit more, but it's so nice to climb into a car that shines inside and out.
