That's correct, yes.
That's one question out of the four answered, so three more to go for the point.
I'll lock it for you for 24 hours though to see what you can find.

That's the car, the engine and from when it dates, yes.
But I have a different company behind it, so I'll lock it for you to dig into a bit more.

Yes it was, so this is now solved.
It was actually going to be a joint venture between Washmobile and Delettrez.
Easy eh?!

[Carnut]

Thanks.
Note the model has 2 extra doors!

You are right. The name was in fact JOYMOBILE I think...

[Carnut]

You're right and that's what I had it as.
I have no idea how the 'a' got there!
