It's funny, I literally had to ask myself this question about this time last year. Obtaining a 52 Mantle has always been a dream of mine (and many others, lol) and I still hope it will happen one day. I'm also a car guy. I already had a 73 Corvette convertible but the dream there was a red and white C1 (58-60). Both dreams were equal to me.
Anyway, last year in the same week the right Mantle AND the right C1 Corvette came my way, opportunity on both. I spent an agonizing week trying to decide what to own...the Mantle, or the Vette. Both same price, both private situations. I chose the Vette. So I guess in essence, I would answer the question yes, I would make that trade (but only for a vintage C1). The Mantle may appreciate in value more (Vette's are slow and steady...) but I will get more physical enjoyment out of the car.
Maybe one day I'll trade it for a Mantle...haha...who knows.
And wow Raulus...HELL of a car...that's everyones dream!!!
