How about my situation then?
I bought my MM from a guy in Germany. Saw it on the German forum and took a punt. hired a van (cost £100), and took the Eurotunnel (£85), drove for 10 hours to near the German/Swiss border (£60 in diesel), spent the night in a hotel (£60), and picked it up the following morning. I paid £4500 and the machine was in a state. Drove home (£60 in diesel). I've spent the best side of 200 hours stripping, cleaning, polishing, renewing, replacing over £600 in new parts and the machine is now a thing of beauty. I don't plan on selling it anytime soon, but if I did and took all my time and costs into the asking price I would be branded a money-grabbing profiteer! I'm not looking for a profit in any machine I restore but I wouldn't want to lose a pile of cash either.
