Here's my take... the service department will continue to service you and treat you right in hopes that you will like the dealership enough to buy your next vehicle there. I bought my last car nearly 3 hours from here because I trusted the dealer, they wanted to sell me a vehicle at the right price and because it was the right thing to do. I think you have to look at the purchase as one transaction and all service visits as another. They're not going to treat you bad in service...they don't get commission. They do their job and 1/2 of it is to get you back in but up to the showroom.
