Value of the Protecto Plate question

[Larry E.]

Here is my simple question>

If no other GM paperwork is available to a car and the only thing available is the protecto plate then>

If the protecto plate IS Authentic and everything Matches with the specific car how much value does it add to the car?

Just looking for a educated guess. Thanks-Larry

Re: Value of the Protecto Plate question

Wouldn't it depend on the car? The value added for say a 64 250 hp PG tan/tan convertible might be little to nothing.
While the value added to a 67 L88 Marina Blue Coupe might be significant.
Is this answer too simple?

Re: Value of the Protecto Plate question

Larry: I have a '66 conv. with the original 300 HP 327 and it's original Muncie. I saw the car when it was one year old, after first being sold & delivered to a GM (Harrison) executive. (It was shipped to Hartway Motors in a small town in western NY. Same place is now Hartway Chevrolet and still doing well.)

I lost track of the car when the second owner's son took it to college. About ten years later, when painted the wrong color and more, I traded my '70 Camaro SS and some cash for it. Here's the fun part: I didn't know it was the same car (that I remembered from back in 1967), until I found the Protect-O-Plate in the glove box. That was after my purchase. I'd say this POP is pretty valuable ($5000 extra?) given my true story, and the shipping docs the owner of the dealership let me copy.

Like Don implied above, there are so many other variables. Hard to say how much extra in dollars (for each Corvette).

Don: Should have explained what I meant by "value". Anyway I was after a "percentage" not the actual cash increase. As we
know your example of the 64 above would have started with a book value a lot less then your 67. I think the percentage of
both should be fairly close though excluding anything so special as a L88. Thanks-Larry

Re: Value of the Protecto Plate question

Larry, as you know, if most of us NCRS nuts were presented two equal cars at equal prices, one with POP and one without, we would choose the one with.
Taking that a step farther--any time you start getting into the often-cloned realm (435, LT-1, L88, LS6, etc.), a car with a real POP steps out of the potential clone realm into real car, and in my mind, changes the whole level of interest in the car, and keeps the field of potential buyers larger.
Percentage-wise? On an LS6 30-50% maybe? LT-1 20%?

Re: Value of the Protecto Plate question

Protect-O-Plates won't call out options like sidepipes, optional wheels or air conditioning on mid years. They certainly will call out engine, transmission and interior/exterior colors. That being said, a red/red 1967 435 would benefit tremendously by having g a Protect-O-Plate, but the sidepipe option would not be documented with this piece of documentation if it were to have it, also.

Re: Value of the Protecto Plate question

Just like the car itself, can't a Protect-o-Plate be recreated and aged by purchasing a reproduction P-O-P, addressograph plate, GM tape, etc., and have it "aged" by one of the vendors that can be found online. I think that due diligence is needed for both the car and any documentation. The nice thing about a P-O-P is that it has the original owner's name and address, and most times the dealer's name and number. This all would be a great place to begin verification of the P-O-P.
I was able to purchase the blank materials to make a P-O-P, but unless I had absolute verification of the original owner and dealer, I won't recreate the P-O-P. For now, I plan to enter my own name and address on it just for fun.
As a guess to the percentage increase in value for a car with it's true P-O-P, I would say 2-5%.

Re: Value of the Protecto Plate question

Is it proper to Certified and Validated a Protector Plate to see if is the real deal and original to the car or a reproduction , basically it's the birth Certificate of the car it will at least clarifying the most important items of the car.

Re: Value of the Protecto Plate question

NCRS does not validate Protect-O-Plates, other sources may confirm them. I'm sure you have the book on Protect-O-Plates, that will help you confirm if yours is original or not.

Re: Value of the Protecto Plate question

Ownership history adds value also. I just discovered my 66 red / black L-79 AC convertible in Hemmings. I bought the car in 1974, [before NCRS ] an sold in in 1977 to an Arizona owner who had it from 1977-2008 when a Prospect, CT buyer bought it a BJ Auction in Phoenix. It was inspected last Wednesday, and is the same car.

It never had the original POP unfortunately. There are many factors in value of a vintage Corvette, and factory paperwork makes it easy to document, even a 64 saddle / saddle 250hp car

Re: Value of the Protecto Plate question

Given the value curve of classic and collector cars, everything out there from a Series I E Type to an air cooled Porsche to a 1970s Lambo - and even most high value Corvettes - has at some time been trading hands at relatively low prices. That means there is a chance all those cars were owned at some point by people who didn't really care about them. To me, a Protect-O-Plate adds value even to fairly nondescript Corvettes (including my '71 LS-5) -- because it increases the likelihood that past owners were thoughtful about the care and use of the vehicle. In my case, I'd say the POP and the other paperwork I have would bring me an extra 5% if I wanted to sell the car.

Re: Value of the Protecto Plate question

of the 32 corvettes I've owned over the years, only 2 had their POPs,the ZO6 tanker and a 66 425 convert. both POPs passed to me when I bought them and both left with them when I sold them. my thoughts on why any c-2 retina its POP : these two owners were obsessive/compulsive. mike

Re: Value of the Protecto Plate question

Mike, your '63 Z06 tanker had a POP? I thought they started in 1965?

Yes i know NCRS does not Validate Protect-O plate Tim, yes i have the book also but I don't have the eye's and the many years of research or knowledge or the expertise to confirm if is original or not and i know there sources to confirm and Certified or validated the POP, so wouldn't it be wise to Certified a Protect-O-Plate when someone is trying to sell there car and advertising they have the original Protect-O-Plate same goes with the Tank Sticker and Window Sticker give proof to originality of the car.
