I think I know the car of which you speak. Nice piece of work indeed but not tag matching.
I think it is also clear that many owners are not concerned about owning a tag matching car so again, it boils down to personal preference. As the owner/maintainer of four classic cars, I know what a job it can be and anyone who puts in the time, effort, blood, sweat and tears ought to have their car as they like it. But on the other hand, being a data maintainer by trade, I'm also a stickler for acuracy and facts so I can't help calling it out when I see it. So... all that being said, back to the topic of judging. Here's one, my dad and I restored a '51 Frazer (F515 standard) back in the early 70s. The car was Mariner gray but dad didn't like gray at all. He kept recalling a yellow '51 Frazer convertible which he saw in the show room at NL Motors in Souix Falls in 1950 so he painted that F515 Arena Yellow (I think I've posted pictures of it on here). He painted inside the door frame, under the hood and firewall, inside the trunk, etc. The only way you know it wasn't original was the tag listed the paint code for Mariner gray. Of course we now have info supporting that the F515 was not offered in Arena Yellow. Point deduction for that or not? I say yes, it should receive a deduction because it was a color that was not offered on that model. By the way, that car survives and the owner is very proud of it. I still see it around every now and then.
