OK I have a 98 clk 320. Yesterday my girlfriend and I got in a fight while driving. She then proceeds to puncture my dash board with her heels. So thats #1....how can I go about repairing a hole in the leather of the dash. It's right underneath the air bag.

#2. I had a uhaul hitch installed on the car and ever since, the muffler rattles when at idle or close to idle. You can also feel the slightest bit of shaking when at idle. (wasn't there before)....any ideas guys?
