The current business model on secondhand warranty/sales does seem to me a bit silly to me by not allowing warranty transfers.
It incurs significant secondary VAT charges which removes money from the buying market. I would think it probably equals or exceed the dealers profits on the SH sale and does nothing to promote sales.
If the dealers left SH sales to the private sector more money would be retained in the buying market giving the seller more purchasing power for a replacement new bike and a happy SH buyer secure in the knowledge it has ongoing warranty, it could possibly speed up sales.
If the dealer still wanted have an input then, dare I say it, 50 cycles system of dealing with SH sales seems like a good way to go about it. The 10% commission on sales covering the increase risk posed by warranty transfer.
The bike could still be subject to inspection prior to transfer approval but if it fails the original owner could insist on the bike be repaired under existing warranty anyway, if applicable, but insist any other non warranty faults be fixed at the owners/ buyers expense before transfer is approved.
I see this as a win/win situation for both the dealers and buyers but then again I could be talking total BS.
I would be interested in what the ebike trade thinks.
