I came across an advert the other day for a G-Wiz. It was a 2007 model with 1700 miles on the clock. That counts as barely run-in - if you ever need to run-in an electric car that is. Either way, 850 miles a year even bouncing around London is on a par with a ponderous commuter cyclist.

It was up for just £4500, which is roughly half the cost new, depending on what extras are added, and even that price was negotiable. What we have here is the realisation that the G-Wiz is a risible mode of transport. The owner might well claim, ‘genuine reason for sale’ but I reckon they can’t wait to get shot of it.

I’ve seen the same happen with some hybrids. At the moment there’s a whole bunch at a West London car supermarket, a triple AAA battery’s throw from the congestion zone, which were all underpriced and not yet sold. I’m slightly tempted to buy a really cheap Prius and run it until something expensive needs doing, but I can’t get away from the fact that I’d still rather have a Golf TD.

Good luck to Tesla with its new showroom that I must pop along to. At least moving the stock around won’t choke the receptionist or spoil those vital sales calls.

I get the feeling, though, that it could be as whisper quiet in there as the motor. A Tesla is no G-Wiz, thank the automotive gods, but cost has to be an issue, as is the future cost of replacing the batteries.
