The tape to fix my window flapping noise came in so I called the dealership. While I had him on the line I asked him about not wanting to pay $90-100 to get my oil changed there because how much they charge for Mobil 1. He said "I hear ya man". But not having a grease gun I asked how much for a chassis lube? $20-25. Not bad. Plus it gives me a reason to go look at new stuff on the lot. I figure with all the money I'm saving by doing it myself I might as well take it in and get the under caraige checked out.
