For "toy" purposes yes. Part of the reason for my saying that is I don't quite know what "are you interested?" means.
If as someone else suggested the question is "what configurations do you want?" then my answer would be "flat 12 because that's so hard to procure in the current environment" and "V-12 for musical reasons."
So back to the original question "would I be interested in having [all those] options" of course the answer is "yes" but how does my saying that help you?
I guess my question back to you is "what exactly are you trying to learn by posting in this forum?" Or put another way "what decision are you going to make based on this information?"
It helps me by understanding the market...for all intents & purposes you guys ARE the market. Enthusiasts who crave something a little different, that's why you're building replicas, customs and one-offs.
There is a much better cross-section of knowledgable users/buyers on this forum, than on many automotive forums spread across the hinterlands of the internet.
We have many folks on here who have worked for manufacturing concerns, own a boutique supplier of goods, raced & placed the originals, engaged in minutiae oriented recreation builds from the ground up...in other words, y'all know your shit! :thumbsup:
