Revell did the E-type roadster, the Shaguar from Austin Powers, the spy who shagged me.
Gunze Sangyo also had the roadster, one simple and one super detailed with etched wheels and a ton of die-cast parts. The detailed one was also issued under Airfix lable. I'd go for the Revell one, at least it'll be easier to find and to a more reasonable prize.
The Gullwing was issued by AMT.
I don't know the availability for these kits but if nothing else maybe you can find them at Ebay
Good luck!
