Used to be a local Chevy dealer (four miles away). Nicest folks, but limited knowledge experience dealing with my C6 Z06.
Then went to the next closest dealership (2nd largest city in the state), and that was not acceptable (oil on door handle, on rear deck, etc.).
Now drive 38 miles each way to another small town dealership who has fantastic Corvette technician. Will be very pleased to have that dealership, with that Technician, service my 2015 Z06. In fact, even though they sell new Corvettes, they agreed to do a courtesy delivery for me (because they know they can not get me a 2015 Z, and because not only do they do all my Corvette service work, but because I have recommended, and now they have my friends take their Corvettes there for service). Regarding the upcoming PDI, they put it in writing that only my Corvette Technician will drive the car and that he will do the PDI.
Wish we didn't have to shop Chevy dealerships, but many of us do. The Z06 will be the second biggest purchase in our lives, and well worth a longer drive to get great service.
