I was up north earlier this week, and while I was there I found a Ferrari 365 GTB4 and, what I thought at the time was, a Lotus 7 kit car.
Further investigation when I got back made it clear it was an original car, a 1985 Lotus S4X.
I found the actual car on Google.
The place where I got the picture from had a bit of info on it too, from the owner!:
Howdy - that's mine. Last of the Steel Bros S4 chassis / running gear + Lotus 907 2.0ltr engine & Elan 5-spd gear box. Built by the ill-fated Bainbridges after they 'bought' bits & jigs.
I can't find any other info on it though...
