Used to have a red MGBGT 1968 wire wheels - the biz - but you're right - see one now and they seem tiny ! Mind you my old Elan looked tiny compared with the Zed which seems a big old lump in comparison.
A mate of mine had one at uni, in British racing green. Was great fun and as you say quite little! The shock was when you drove it and tried to brake hard... They were terrible! Brake technology has come along way since then!
