What would you do in this situation?

If you have an other Dealer you might start going them. Or ask the dealer what happen to the muffler and have them pay to fix it. Point out the dirt (might be to late for that) good luck.

Good Luck. You are likely just screwed, but I would email the shop owner, and include pictures. Many years ago (1994) on the way home to Missouri from Colorado, I stopped at a Husqvarna dealer in Kansas City, Missouri. (Missouri - not Kansas, so no one mistakes which dealership I'm referring to.) They had a new 1994 Husky 610 that I liked. I drove home to St. Louis, and checked at my local dealer, but they did not have the bike, and neither did any other dealer I called. I called the K.C. MO dealer about 2 weeks later and purchased the bike over the phone. When I went to pick it up, it had obviously been ridden - quite a bit - knobs were worn, and dirt was in the places where it was difficult to get out, air filter was dirty... I thought like you that they just tested it. Then I was told that the MSO needed to be replaced. It took me 6 months to get it, and I couldn't title the bike until I had it. When I drove to get the MSO, it was a replacement, and the dealership had no record of the several hundred dollars in spare parts that I had ordered and paid for when I picked up the bike. When I told the owner's wife, who was the shop's "CFO" she said "We'll see about that" in a tone suggesting I was lying. I went out to my truck and brought in my receipts - without them, I would not have been given my parts. My guess is that they sold the bike, the financing didn't go through, the owner wouldn't return the MSO, and the dealership didn't give a damn. I haven't purchased anything from them since, and I never will.
