Just depends if you like some burnout, who does not care, to damage your car at the dealer. I would pull it into service, go over the car with the service manager and camcord the cars condition. That way when you get it back, and it is damaged, there is no dening it by the dealer. otherwise they will say they did not do it.
I have had 2 cars damaged at different dealers from leaving them there for just general work for just for a day or a few days.
You just can't control who has access to them, who moves them every morning/night and such. Most of the people who work on these cars and at the dealer just look at them as just another car and don't care. After all its not there hard earned money that bought the car.
The only people I let touch my car is Roe Racing and the dealer in town where I personally know the salesman, service adviser and vipertech. I drive 35 miles to this dealer for warantee work, when there is dealer 3 miles away, but it is worth the piece of mind.
My examples:
1) my first 1997 GTS, brand new 21 miles on it, bought it in late 1998 from woodhouse. Took to local dealer for oil change. Car Porter that moves and washes cars, decides to show the engine to his buddies at lunch. Slams the hood down upon closing and cracks the right corner on the edge of the headlight. After 5 weeks of complaining and the dealer dening that they did it, I got a check for $14,500 for the hood and repaint. I sold that car.
2) 2001 GTS, Dark Saphire blue color, clear coat scratches show very easily just like black. Had failed water pump, on a Wednesday. Took car to dealer on Thursday, viper tech off until monday. Picked car up monday night, car had no gas at all, completely empty. Pull into gas station under neon lights and every pannel on the car was scratched. Another God **** nightmare. Went back to dealer, they said "someone was tring to be nice and washed the car with on of those hard bristle brushes", Dealer attempted to buff, clay bar and such the scratched out. They would be gone temporarily unitl you washed it a few times and the scratch hidder would wash out of the scratches. Did not have to battle them about a repaint because the car was taken off my hands for other reasons. But you can bet it would of been another bitter battle like above.
Its one thing to damage your car yourself, you can live with that. But when you are paying someone to do work and they damage your car, that is unacceptable.
