Odometers stopping for a while is a pretty common failure on MB's, at least on the 124 chassis I've seen it a lot. Odometer rollback shouldn't be that common except by unscrupulous dealers. CarFax can find this but doesn't always - just because CarFax is clean, doesn't mean it *wasn't* rolled back. There was an 87 300D for sale this summer by a dealer in San Francisco with "98kmi". CarFax showed it had 200kmi+ and spent most of its life in the northeast rust belt, when the odometer froze (same reading for 2+ years), then it somehow lost 100kmi. Oh, and they wanted $9k for the car! Some poor sucker bought it - wish I could have contacted the new owner so they could sue the pants off the dirtbags.
