Very nice! I would love to have one of those but I haven't seen any of those 1/18 version by Auto Art for less than $125. Great detail though.
If you think about the average 1/18 style diecast car, it's just a metal shell, glass(plastic), and interior tub, chassis. This one requires a lot more detail with the gas tanks, custom interior and the engine is more detailed especially with the supercharger which is a one off because of the scoop. Might be worth the $$$ but still a lot for a diecast when you're used to paying only like $20 or less for one.
The closest I have of one of those is in 1/24 scale. I have a Cavalier model kit that someone mangled and might bring it back to life. I did make an Interceptor out a 1/24 scale Chevelle. Looks ok from like 20 feet.
