Luc, IIRC Tornado prides itself for selling a "complete" kit...everything you'll need to construct the chassis, interior and body, including glass. I don't think they include the motor or drivetrain components, wheels and tires, liquids, etc., but if you're looking for the kit that already contains most of what you'd need, I'd suggest contacting Scott about a Tornado.
I understand the desire to get as complete a kit as possible. As I read through the build threads I see a LOT of custom fabrication, some of which can be accomplished by the builder (look at Bill D's RCR build thread...he did some splendid work!!!), but I have very little knowledge regarding fabrication so farming all of that out to run the price up a LOT!
Now, if you're a competent fabricator, that opens up a whole different kettle of fish!! :thumbsup:
Cheers!
