cudaman, thanks for the tip. I took my XF to these folks to replace a dead bulb (passenger-side low beam), as neither I nor my regular mechanic could get the dead bulb out.

At this dealer I was given a quote of "about $20-$25" in labor, and about a half-hour wait.

After 1.5 hours, the car was brought up, headlight replaced. The guy working on it had a rueful grin. In order to replace the bulb, he had to pull out the entire headlight assembly from the front. To do that, he had to drop the front bumper.

I braced myself for the bill. But he still charged me only $25 for the labor!

This dealer gets my vote.
