Hello everyone, this may be a stupid question, pardon me as it's my first time buying a car of this capacity. Is it common for dealerships to give courtesy gifts/discounts on service, etc.. as a thank you for doing business them? (Like waiving cost of service to add after market wheels for example). I know it is common with family vehicles (free winter mats, free oil change, etc) but not sure in the case of the Corvette. Thank you!
