Certainly not a car for everyone, but it will retain more value, over time, as compared to any other kit car.
Just as Kirkhams are not for everyone, just as FFR's are not for everyone. I am pretty certain there is not one of the representative cars which can be all things to all people. Could be why there are so many makes to chose from today.
Just FYI, these cars will see track time. Yes, some will be hid away by collectors, but even $100K Kirkhams are put on the track.
One of my friends owns a Kirkham, a McLaren F1, and a Ford GT. He tracks all of them. Not everyone hides these collectibles away.
Cobra owners are an odd lot. None of them really think their car is better than another one. Instead, they pitch in and help everyone make each car as good as a representative of the model as it can be. Kirkham, Superperformance, and CSX owners all work hard to maintain accuracy of the car. Everyone else does what they want to make their car, their car.
I know people who are drooling to get one on these. I hope they can.
