Is there any data out there on what percentage of new car buyers take their vehicle to the dealer for maintenance? I've found myself in a position where I can't do my own maintenance for the first time in many years, and after waiting 3 hours for an oil change 3 different time at 3 different dealers I doubt I'll ever hand my keys to a dealer service department ever again for any non-warranty work. And this is on top of their extortionate pricing.
