I take it to a mechanic in Huntington Beach. They are called Zito's Auto Care. They can do a lot, but not everything on a mercededes. For example, I need new plug wires, so I have to get them myself, then they will replace them. Real good guys, real honest. Only on a rare occasion do I take it to Fletcher Jones MC NB. I take it there when Zitos can't help me.
Anyway, it was determined the spark plugs were bad, as were the plug wires. They are changing the spark plugs with OEM Bosch plugs, but I have to get the wires (I was quoted at $106 for the whole deal, is this a good price?), and they will install them. Where do you work ?
