No idea. I love that car too, but it wouldn't be hard to clone, minus the grille. But then again, I'm not a 55 Chevy aficionado, so that may be a common aftermarket grille.
I'm young I dont have the cash to build a car like that. it has to be somewhere? or maybe its still sitting in the back lot.
I like the car also. I love almost everything Stephen King has done, very talented guy and decent taste in cars. Christine, the Toronado in The Dark Half and this one at least.
