I had the option to buy one a couple of weeks ago with 8 months test left on it. It was advertised at £110 and the seller was only willing to drop to £95, it did look in good condition but by the time I'd spent £20 on fuel picking it up and another £40-45 getting it tested (keeping my fingers crossed it would pass) I decided it was worth spending another £20-25 and getting a new one delivered to my door.
