I have to say that I agree with Peteuk001.
My Commando which I have just finished totally rebuilding to exactly (nearly) how I want it cost £3,500 to buy, and with repairs new parts etc has totalled over £10,000 which is about $20,000 U.S. I know that I will never get my money back, but that doesn't bother me, as I wanted a Commando as mine now is.
The main error made by me was buying the bike originally at too high a price. I believed that because the tank and side panels were very well painted, and there was quite a lot of stainless on it that it was likely to be in reasonably good condition elsewhere. I didn't take the time to look. In reality, I paid at least £1,000 too much for the machine, and found to my cost that most of the cycle parts were worn out, the wiring was atrocious, everything was basically tatty or damaged. As I said, it was my own fault, as I didn't take the time to look.
I knew that the majority of Commandos that are on the market would probably cost me £3,000 to £4,000 on top of the purchase price to get as I wanted, but I have surprised myself with the £6,500 + bill I have generated. I have to say though that I am very pleased with the end result, but if I were ever to buy another, getting one that is already sorted would be a priority.
