Honestly, no idea. 'Affordable', perhaps?;-)
No, but I think I'll give you this and tell you since you have identified what it is and who did it, as I asked.
I found another picture, below, which said it had Gullwing doors and describing it as the GM Gullwing Sports Car!
Although it looks almost identical to the puzzle picture there are slight differences on the sides so it may be that it's a different version and only this other one was a Gullwing proposal, hence I'm calling the puzzle solved.
Well done!
