Yes, KITT had everything in the package, but I'll tell you, it was an engineering nightmare trying to figure it all out. I pondered on it for days on end when I was in my twenties. I'm a 45 year old maintenance mechanic, and trust me, where there's a will.... If I had the dough, I'd build one wih ALL the features, just to say I did it, and prove it could be done. The hardest part is the T top section with the brake panel that pops up. The rest, even the convertible, is easy in comparison.
It would be something that I would only attempt ONCE, for obvious reasons!
