At one time we owned two used Mercedes. I loved the Diesel even though it was a tank and and had no acceleration getting on to a highway. When the brakes went on it I just thought it was one of those things. The mechanics at the shop we took them to for service did become a little concerned when the second one developed a leak in the gas line, flooding the car with fumes, while I was driving down the Turnpike. For some reason they wanted to know if my husband had a large life insurance policy on me.
