I like this a lot. The only Airfix E-Type I know is the kerbside 1/32, can you tell me more about the donor kit you're using, please?
It's a reboxed Heller kit. Heller did roadster, coupe and race coupe (the one shown here) versions, all of which are full detail. AFAIK, only the race version was reboxed by Airfix, but the regular coupe has been reboxed by Gunze - not to be confused with Gunze's own roadster kits. The Gunze & Heller Jags are by far the best plastic kits of these cars in this scale.
