IMHO, I think it is perfectly valid at this point to name names.
My dealer, Byers in Columbus, OH, has competently, although expensively, performed all the work I have had them do. Granted, most of that has been warranty work - switches, window regulators, the usual VW electrical gremlins. The oil changes are obscenely expensive - $110, but they use the correct oil, and used to wash and vacuum the car. They no longer vacuum.
But, any corrective work I have since sought out gurus in the area. Byers, last time I looked, billed at $98/hr for labor. This is why I avoid them now. That rate is simply unsustainable for me. They have in the past quoted $900 for brake replacement, and $285 for a replacement key fob.
OTOH, they have sold me an OEM battery for $95 - fairly priced. Their oil and misc filters run around $12-15, IIRC. They did however want $100 to install the battery, and quoted $75 to replace the brake light switch. Oh, they have also quoted $75 to replace the headlight bulb, but acknowledged that this estimate DID include the cost of the bulb.
So it goes.... I have no doubt they would have correctly installed the headlight bulb in my NB, but again, labor price structure for this dealer is, IMHO out of line and not supportable.
