When I first got the Mercedes-Benz 190E 2.3-16 Cosworth home, I reached out to the dealership in Pennsylvania that was listed on the service reminder sticker in the windshield. I asked if there were any records of repair available, to which the service manager confirmed that yes, they did.
Amazingly, the service manager said he'd send me copies of the records they had on file, which were surprisingly complete. Now, most dealers will never release the service records, so I'm forever grateful this advisor agreed to do it. I look at the report every now and again, which confirms the 190E was well maintained before it ended up in the hands of the last owner before it went to the salvage yard.
The most interesting detail is that it dropped a piston at just over 66,000 miles. In terms of the Cosworth engine, there's not much evidence that the DOHC mill has a tendency to burn through pistons. Although the details are sparse on the service reports, I've always been curious how extensive the repair was, and if the dealership made other fixes "while they were in there."
We'll never know for sure what else was fixed at this time, but it's a fascinating anecdote in this car's colorful history.
