dion rings a bell...or something begining with a d

Is it a kit or is it an ex race car, if the latter there are literally 1000's to choose from!

I don't think it's a Deon if that's what conrodkid was thinking of, they did a Dino rep, but don't recall anything looking like that

If it's a race car - that looks like a race type fuel tank in one pic possibly? - then I would think Chevron is a strong possibility, tho' again there are an awful lot to choose from over the years. Pretty sure I recall Chevron using that sort of "double bubble" roof?

Definite similarities with the Chevron B8, tho' the B8 doesn't have such a pronounced roof line & is different around the front of rear arches - I would look at stuff from that era

Do a search on Davrian. I seem to recall their Mk7 was a similar shape.
HTH.
