I'm a Cobra guy in the core - I'm building two right now. The GT40 is just the absolute driving machine, just not open.
Easy to get tickets with it, so before I start collect any of them the car goes on the block.
However, as much I like to drive them - as much I enjoy building cars. The 289FIA was a scratch build...
