My '67 230 SL (coincidentally, which has a VIN very close to the car in Poland that Flyair flagged) has been undergoing an engine overhaul and some mechanical fixes for the past few months at the Van Dijk shop here in the Netherlands. Now that the engine is back in and the work is largely done, the appraiser came by the other day and I was pleasantly shocked at the value he gave to it: EUR 85,000. He said in Germany, I would fetch over 100K.
Granted, it is a very clean car, largely original, fully documented and now fully restored. But I was still surprised. I had been expecting maybe about 60-70K. I'm happy that I may one day recoup what I have invested in it, if I ever sell it, but it also makes me a bit sad for those who love these cars and can't afford even a decent driver at today's rising prices.
