Self driving cars will drive themselves to to dealer for service. Until then i have to admit that the dealers have gotten stronger in their market retention. I've had even good customer "say goodbye" after buying/leasing a new car. Free loaner cars,scare tactics, lifetime warranties, $19.00 oil changes, free car washes, coffee bar, etc. I would check out the dealers in my area and see 30 people waiting for their cars. It's a war that's for sure.
