Love the colour but I'll go '
no comment' on the interior (apart from saying I'm sure Liberace would've loved it).
I can't blame them for pitching it around the £20k mark, which only puts it up against mid spec Caterham sevens in the marketplace. I personally think a lot of these cars get undersold. Before deciding on a price just stand back and really
look at what you've built...
To me there's something not quite right about the wheels too. I think it's because the hub centres stick out too far rather than being recessed like Borranis. They didn't need to be chromed either, although Borranis have chrome spokes the rim is alloy. The owner would've got a more authentic look by using the MWS Aston/AC/Morgan wires (see below), which come in at about £1,100 for a set of four including custom splined adaptors and three eared spinners as I recall. Looking at the wheels that are fitted though, the MWS ones would possibly foul the arches on the MX250. Worth checking though.
