 I will never own another Mercedes.  My 2006 C230 caught fire.  As it turned out it was still under warranty as I had purchased the 5 yr/100,000 mile extra.  I had it towed to Hoehn Mercedes Carlsbad. Adding insult to injury I was told it was their opinion the car caught fire because I ran over a cigarette butt so the warranty was void. I contacted Mercedes directly.  They were equally as insulting and unconcerned.  They told me it could take months to ever really figure out what started the fire and in the meantime the warranty was void. Needing to move on with my life, I filed an insurance claim. They intend to get to the bottom of this.  This experience has been most disappointing.
