i took my car ('92 400E)to the local mercedes dealership yesterday due to the fact that it's still hesitating and missing. they diagnosed it as needing new spark plug wires and quoted me only $1400.00 for the job!! now that would be approx. $700.00 for parts and the balance would be labor.....fastlane wants approx. $200.00 for the wires, $2.50 for each plug and $12.00 to ship it two day air......hmmmmm, i wonder which way to go.......
