I find this an interesting thread for many reasons. Harkens right back to some discussions in the past on this forum. It will be the eternal issue in the car hobby. And with it comes the unfortunate and unnecessary snooty attitudes. I think the true aficionados enjoy their and any other car that their owners enjoy having and tinkering with, regardless of heritage or pedigree. I think many people derive some kind of sense of propped up self from their prized possession, which inevitably leads to claims of superiority or inferiority...depending of which side you're on. But take Jay Leno as an example of an enthusiast: arguably could own whatever he wants, but drives a replica 427 Cobra... Among the many "original" cars he has. The discussion is tiresome...
BTW, I have one of those leaf sprung 289 FIA Kirkhams... It's a great, no, fantastic car... My good friend Ron owns CSX 3106..., he must be a better man!
