Charlie that's a great question. Yes it is my favorite so far. The decision you need to make is whether you want a vintage look or not. I have done 2 RCR 40's, had a Superformance 40, an SLC and have probably built like a dozen cobras. So I have had vintage and concept both. I am frankly, just tired of the vintage idea for a lot of reasons. The SLC would probably be as easy to build as the GTR so that is a personal choice. I really like the looks of the GTR over the SLC and I can see a strong secondary market with the track guys I run around with who own Ford GT's.
As for the build, it is a very easy car to build if you stick to the plan. A lot of guys get way off the main path with their car builds. They do some very nice, very cool work. You don't need to do all that to have a great dependable car. This is also the biggest car I have built. I love the idea of not being cramped inside the GTR.
I've done a lot of different cars and this one is on another level.
