Bet you get a guy enquiring about the ECU as I did when I was scrapping my accident damaged W202 C200 last year. That's assuming you have the earlier PMS type engine management system. It it does have this it'll have an electronic fairly flat(ish) box underneath the windscreen washer bottle. Mine didn't as it was the later HFM version. Those ECU's cost an arm and a leg from Merc and generally fetch 200 / 300 pounds on ebay.
Might be interested in the electric aerial complete with mast, assuming it's working ok. How much do you want for it ?
