What's it Worth Premium for numbers matching vs NOM

[dadsbee]

Probably 50% (of the top dollar cars) are restamps anyhow. No where have you stated what year you are looking at, 67 back the best you can do is line up all the casting dates, assembly dates and SO stamps and be happy.

It’s not that I don’t care. Perception is perception. A different engine block is a negative for “mopar guys”… but 80% Asian sheet metal from 2026 and “numbers matching” is more original. I’ll never understand it.

100% with you there.

Numbers matching car with a bunch of Asian stamped sheet metal is just another normal car in my book.

Sure, I would love to have an all-matching car with pedigree, but then I would be too scared to drive it or leave it parked anywhere.

My basic philosophy: I'll offer you what I'm willing to pay for the car/part, if it's enough, ok. If not, sell it to the next guy in l line.
Yup, just made it up the first rung of the evolutionary ladder, just began walking upright.

You say the seller of this car you are looking at wants a 75% premium because it is matching numbers ?
Well it will come down to who else believes it is worth that much more ??

If no one else does the seller will own the car till he drops his price but it sounds like you want a matching numbers car yourself
If you buy the car as the price comes down that just means no one else will ever pay that much extra for the car if you are thinking about a future sale because you wanted it the most and was the person to buy it now

There is also pride of ownership that will have a value to you so how much is that worth ??

I know I felt like I paid too much for every Charger I ever bought but time was on my side and did sell them for more than I paid in the end

It will come down to how much time you have to own this mystery car ?

Your money and you can not take it with you when all is said and done

I’ve wondered if this car is actually for sale or not. Sometimes you can see it’s about “I have it and you can’t, unless you massively over pay”

It’s a stamped car. Easy enough to decided if I believe it was done at the factory.

That’s really great guys that you don’t care. The market does and that’s all that matters. If I could fork over NOM money for this car, I would.

Years ago, I had many clowns approach me and low ball my well preserved original GTXs because “they didn’t care about numbers.” When I actually sold the cars, numbers and documentation were an issue.

I own such a beast, but I drive it. You know the story. But in my case, resale is not a factor. It was with my earlier cars.

You would think, but trust me it's not!

When you buy a car numbers matching and are worried about resale value only, you are investing in a collector car just like a person that invests in stocks. Just like stocks prices go up and down on many factors. With a collector car, prices recorded at auction are just as dependent on matching numbers and what options as who came to the auction and what they were looking for. Just from my experience a 4-speed and a convertible are two of the biggest options as far a resale value.

Good luck on your investment strategy, but I personally buy a vehicle to enjoy and bring back a few memories. To buy one as an investment as the primary goal, I think you would be better off finding some stocks.

I would more concerned about the restoration. A lot of restored cars are lipstick on a turd

So you have seen that some people aren’t that concerned about having the original motor. You DID ask for opinions. Ultimately you will go with your own educated decision. The way it should be.

This is the sort of thing I don’t get. You created a strawman argument to down me for no reason other than some sort of smug bs only understood by you. Where anyplace in this post did I say one word about investing, market return, flipping, or the like? I’ll save you the trouble, I didn’t.

Next car you buy, you be sure to pay 15 times market value because you “don’t care” about value. See how stupid your input was? Well actually you might not.

Yep, I asked what a numbers car was worth vs a non numbers car. I’ve reiterated that a few times. Unfortunately, more than a few can’t read and also want to put somebody down to make up for some sort of shortcoming in life. How does it add to the post to show up and post that you don’t care about the topic? They need to think of this post when buying a house or a car and remember it doesn’t matter what that feature or swimming pool is worth, so just pay whatever is asked. Sound stupid? Sure does, that’s what this kind of input is.

For many cars and most of the population having matching numbers comes down to being able to gouge more money for the same car.

Probably 90% of people don't care.... most Chevy and Mustang restorations claim to be Matching Numbers, but there are not many ways to prove it....so plenty get away with unsubstantiated claims. Ma Mopar did the future generations either a great service or in some views, a great dis-service by naming, numbering and dating nearly every part. Now we have threads started by clowns who are worried about the date code on a throttle spring FFS.

Sure it's nice to have provenance, but really in a couple of years it won't matter much at all to anyone but the finicky few.

I thought all Chevy's were SS cars?

 

[RemCharger]

Basically I’m looking for percentage that numbers car is worth over the rest since I know the prices.

Yep, I asked what a numbers car was worth vs a non numbers car. I’ve reiterated that a few times.

I'd have to agree with the posts that addressed the question, about 20%.
But at the same time, every car and it's price is unique. Not like comparing 2 new hyundais online.

 

[chargervert]

I don't think that a 383 car with its matching numbers engine is in the same league as a Sixpack or Hemi car with its matching numbers engine. The percentage is a lot higher if a Hemi car has its matching numbers engine versus a 383 car. On a 383 car maybe the percentage is 15 percent and on a Hemi car it could be 30 percent. I would also say it's more critical in the current market value wise that a Road Runner or Super Bee has its matching numbers engine versus a second generation Charger,Chargers sell for crazy money regardless if they have the matching numbers engine or not.

 

[Some Car Guy]

The gist I’ve gotten from the legit responses here and elsewhere is it’s about 20%. You then have to get down to the details to go up or down from there. My rough rule of thumb had been a 4 speed NOM is pretty close and in this case it was on my low end personal estimate of 20% on the 727s, not the 30% I’ve noticed because it had some condition issues.

So I tend to think this car would be slightly above that and that would follow consensus thinking. Unfortunately I think this will be another one where I point all this out and am told my offer isn’t welcome. I’ve had several cars over the last few years where that has happened, and the car remains unsold on the market. One that sticks out is a 68 GTX. Car was auctioned at least 4 times and we had those public numbers to go off of. I offered a decent amount over that I felt the car was reasonably worth. Guy was like 40%+ north and still had the car last I knew. Just one example.

Sorry been fixing, selling. building cars for over 50 years. Seldom do I see a person concerned with numbers matching that was not concerned about resale value or just enjoying the car. And I also get a lot of people saying a car is matching numbers when they don't look at the things that really make it numbers matching, like the Alternator, starter, wiper motor etc. Matching number cars are very rare because after being driven and worked on for decades things break and get replaced. Numbers matching makes a car valuable because it means it is an unmolested example, which is very, very rare. If you were not concerned about the car in question being an investment why worry if any of the numbers match just buy it and enjoy it.
I have gone to a lot of work many times for example building engines for people so worried that the numbers on the block need to be correct that they get an engine not nearly as good as it could have been if they had just used a block that did not need a sleeve, cracks fixed, or other expensive work.
I just finished a 340 for a 71 Cuda that was stroked with a hydraulic roller and ported stock heads, because he had to have the right number on the side of the block. It is a great engine that makes over 400HP with a smooth idle, but what I would have done is stored the original engine built a stroked a 360 and got some aftermarket heads and it would have made 500HP for the same money. But again, he wanted to brag to anybody that would listen the numbers are correct.

And I don't buy completed cars just because of what I have seen over the years, and if someone tries to sell me a car and the term matching numbers comes up, I simply walk away, that is not a game I play. One time I was asked to rebuild a numbers matching 1964 corvette that was smoking. When the engine was removed and the block cleaned the casting numbers were made out of body putty, instead of a 327 it was a 307. We got an engine with the right casting numbers and I thought it was an exceptional car when finished, but the owner was involved with lawsuits and all that comes with it, got sour on the car and sold it. How much did it cost to get the right block and heads? less than 500 dollars, wonder what the lawyer charged?

 

[YY1]

I've found in general sellers don't want to hear, nor do they care about hearing what is or is not correct or "wrong with" the car they are selling.
In fact, that's almost a sure way to immediately start souring them to dealing with you as a potential buyer.

Make an offer based on what you've observed and researched.
Either it will be accepted, refused, or countered.

The one way I've found to "sort of" get around this is to ask questions about areas you are concerned with and then frown when the answer comes back.

Me- "What's that hanging behind the AC control bezel?" (bezel was empty)
Seller- "I think that's an aftermarket AC controller"
Me- (frowning) "Hmmmm".
Me- "I think I can see the factory controller hanging there, as well.....Hmmmmm" (again frowning).

Of course, they already know (or should know) all this.
...but this lets them know you now know it too, and they are involved, basically admitting it.

If you were talking to someone on the street and somebody else came up and said “screw your interests in life,” you’d say that guy was an asshole, right? You’d rightly say “who asked you about your personal tastes?”

Look, you fancy your thoughts as being important, we get it. They also mean **** to me. All I asked and was trying to do here was gauge what is normal and customary to pay for this sort of thing. I didn’t say anything about being told I’m an idiot for what I’m into or what do you do for fun. I’m not a guy that asks for permission to enjoy my life as I see fit.
