Rune,
IMHO, those who strive for a true replica will be envious of the GOX chassis. I cannot afford one. I know it, and am happy with a tube frame replica. For me the MDA is a good purchase for me. I know it is not 100% accurate and I know MDA will agree, but it is a good kit. The replica market caters for many buyer, true perfectionist GT40 replica owner to those that settle for less. I for one would want a GOX chassis if i could afford one, but I can't. Be sure, you are one of an elite few. Just make sure the rest of the build stands as true as the chassis. Good luck and I hope to see the car some day.
