Ferret is a good chap, excellent work, did a really good job of fitting indicators to my Honda CB77, when I purchased my one owner from new Comet, all the cabling, front to back was perished, there was only one person to call, Ferret, but sadly things did not go so smoothly the second time round.
Previously when Ferret worked on my Honda it was all done in my garage which was great, when he turned up to work on my Comet he immediately said he would have to take the bike away as it could not be done in my garage as I did not have a work bench, I did offer various alternatives like 2 x Black and Decker Workmates and a board, but that was rejected, it was put to me that the bike gets taken away for a period of time and then returned or not done at all, I did not know enough about his security arrangements or insurance to allow this. I trusted Ferret completely, but I do not trust everybody completely, Vincents do get stolen as we know, so Ferret and I did not see eye to eye and things were a little frosty when he drove off, he felt I had wasted his valuable time, which to a degree I did understand. This experience does not in anyway detract from the quality of his work, he knows what he is doing, just establish with him first whether he is doing the work at your property, or taking the bike away, then you need to make your choices.
