Blurring the line is probably a very accurate statement. As a vintage car guy I try to make sense of your passion. Let's take the Ferrari 250GTO as an example.
In the old days, there were conversion kits based on Datsun 240Z basis available. Pretty spiffy actually, with fiberglass body and many bits that made such a car look . . . um . . . pretty accurate when it drove by. And that inline six sounded not so bad either. But then there were guys who bought Ferrari 250 Pininfarina Coupes (when they were still cheap -- I bought one for $25K) and 330GT 2+2 models in not-so great condition, often with rust and/or accident damage, and send it over to Italy where true craftsmen made a GTO out of it. We're talking genuine Ferrari VIN, with a new, hand-built space frame, new, hand-built alloy body, new interior, and rebuilt and upgraded Ferrari drive train. For all practical purposes, what came out on the other side was a genuine GTO that could only be identified as a Franken by checking the numbers and by diving deep into details. I don't remember the exact price tag for such a car, but I think it was around $180K all in. That's not exactly chump change, but compared to the $5M a GTO back then cost (now it's $27M), it was a steal! Shipping it back to the states was easy, as it was based on the VIN a round-trip for "servicing" in Italy and driving such a car was every bit as exciting as driving a real GTO, perhaps even better, giving the anxiety one must have when driving a multi-million dollar Ferrari among texting moms in SUVs.
In this light I see your hand-picked Rolexes, and although I still own 2 gens (a 16013 that it too mint to wear and my late dad's YG Oyster), I'll be putting them up for sale soon now that I have tasted blood with my first two quality vintage Panerais. My budget is a bit limited right now as I'll be buying a house in a few months and need my $120K down payment ready, but later this year I would love to look out for a highly patinated vintage Rolex or Tudor. "Like new" doesn't do anything for me. I like cars, motorcycles, watches, even houses that radiate history, would be able to tell an exiting story if they could talk.
Thank you for sharing.
