I agree with deanyel. When mine bit the dust last summer at 145k, I had my local independent tech rebuild it. He spent 14 years at the dealership and had already done a hundred or so...

For what it's worth, Adsit doesn't have the world's best reputation for standing behind their wares (from the Ritter/Easley list).

Another option, of course, is to buy a genuine MB-rebuilt. It'll cost you more but would have all the newest updates.
