Way back when I got my '05 I had the selling stealership take a flyer at activating my DRLs. They were clueless about the Starscan tool.
Then one day on my way to work a 300C falls in behind me on 202N and his DRLs are on. So just on a whim I slow down and let him pass me and sure enough there was a stealership surround around the license plate. I call them and did a quick run over to their location. The service manager did it himself. Nice guy, but I can't remember his name, after all it was about nine years ago. I gave him a couple of Cuban cigars for his trouble.
The stealership was Frank C. Videon in Newtown Square, PA, 610-356-7000. At the time they were building a new place out on the West Chester Pike, but the old place was right in Newtown Square.
Give'em a call.
