Hi Tadgh,

Classic Merc coupes are so hard to value and a W123 is a hugely sought-after car. You’re likely to get interest from Mercedes fans over the water in the UK, not just at home, making its price hard to predict. Ostensibly more glamorous Mercedes coupes, like the C126 SEC and the C107 SL from the same era, command prices from €15,000 to €30,000, while later 300CE-24s might be more like €6,000-€7,500. We’ reckon on your car being around the €10,000 mark, maybe more, if you find the right enthusiast buyer.
