I certainly would like to build one but I've built at least one of everything. Cars, bikes and planes from either kits or frame up. I won't recommend a specific kit but just add this. Don't base the finished price on anything you are told by dealers. If you build a Factory 5 with a Roush 427 and a spectacular paint job like the guy in Yuba City (forgot his name), then after parts, registration fees, taxes and the other expenses I would guess you would be into it a little over 60K.
Do the paint work yourself, and get a local engine builder and you can drop the build price to 45K with fees.
Come to a NorCal breakfast and check them all. I know there are Superformance, Factory 5, ERA, Shell Valley, Backdraft, and I think a Hurricane as well as others I'm not familiar with. You will walk away dizzy!
