Sure an interesting thread. I have experience building custom modelcars, and I could make replica's of example Jabba's cars (if thats what you guys would be looking at).
AutoArt makes yellow Diablo Roadsters, and HotWheels makes red F355 Spiders! I have both:
(note the F355 on these pics is a rare UT)
Some examples of details that are missing on these models would be licence plates, the yellow wheels on the Diablo, the 2 exhaust pipes on the Diablo and the interior colors on the F355. Also maybe someone here could design a special box which can hold the models, and maybe Jabba has time to sign a bunch of numbered certificates??
Just some ideas, these models are 1:18 though. I think the total price for one completed set could be around 125 Euro ex shipping...
Let's see who likes this!
