I can only speak as I find...........
earlier this year I let Mike1965 have a bike which was VERY well used and my grandson had grown out of. In exchange he serviced a bike I had just bought from someone else on Wiki. He came and collected both bikes and returned mine to me. He struck me as a genuine guy and not someone who would rip anyone off.
(with some of the stuff getting advertised on these boards for Sale
recently, I would say that Mike1965 was the least of your problems)
