I would love to but renntech is like most mercedes dealers ,,,,what us work on a chrysler, I don;t care if it does have a mercedes motor in it, they didn't say that quite that way, but that is how they meant it,, I live very close to renntech shop, been there twice ,,left both times without any help. oh I know the driver of that slr,, his e55 also turns in the 10's... jim
