Austin 7 Swallow
 

I saw this recently at the Coventry Auto Museum. It made me wonder if it could be done on a Suzuki Jimny chassis? Small, tall, sit up and beg. The Jimny is a little wider and a little longer, but it could be a goer. The JC Midge Mk2 used the Suzuki as a doner, but it looks like it never took off.

Slightly Noddyish I know, but in that colour, and with the aluminium bonnet, it just appealed.

Think the jimny just sits too high personally unless you completely change the suspension

It is high certainly, and it would never pass for a replica, but it can just about look OK.

I suppose if you build it in such a way the body is lower or panels extended lower to offset the midge high body look you can pull it off
