I`ve been reading these comments on crazy prices with interest and as stated already they are only worth what some ones going to pay for them. There is some over priced grey porridge out there, but I can remember being offered a DBD 34 back in 1974 for a crazy £1,000, I bought a new suzuki for £340.
This is not an attack on the fantastic hand crafted personaly built machines that are loved and cherished by the owner,but when it comes to the gold star the real thing was also hand built by the competition department at Small Heath. The genuine thing comes with a dyno test record, they run like a swiss watch, the sweetest thing to ride, fantastically exhillerating on twisty roads. We also shouldn't forget it was the most successful production racer Britain ever produced.
There are two sides to the coin, the cost of good restoration is now very expensive and I would say there are also some under valued bikes out there.
