There was a thing in one of the UK classic car magazines this month about "youngtimers". Merc is the first to actively deal (buy/sell) it's old stock. Obviously top quality at top prices. But essentially, W123s, 201s, 126s and of course 124s. Factory warranty and all that stuff. MB have set up a special unit to do this and aim to run it through selected delaerships.
Germany at the moment, if it works, broader than that. Wonder where this puts the Classic Centre? Probably on alert as to what they'll be rebuilding and getting asked "correct detail" questions in 20 years (assuming we have any oil to run them)
