It must be tough when you can't even remember what you said. Here. I quoted it for you.
This claim turns out not to be correct.
If you want a collectible antique machine gun, you might pay $30,000. Which isn't going to buy you a house. The average home price in the US is currently about $350,000.
You can buy a 1987 Yugo for $100. The fact is the average new car purchase is about $48,000. Because most people do not want a stripped down, bare bones, entry level car. That average is far more than the $1500 or so you can spend on a brand new full auto weapon. In point of fact, that average car is enough to buy 32 $1500 full auto weapons. So I am not "trying" to prove anything. Your claim is wrong. That's proven.
If you want to compare prices, it's foolish to compare the price of the cheapest piece of junk used car you can find (the Yugo) with a brand new full auto weapon (a full auto AR-15).
Average price for a new car in the US is about $48,000. Your entry level stripped down Civic is $25,000.
Average price for a brand new full auto Colt AR-15 is about $4000. An off brand is $1,500.
Average price for a collectible 1940's era machine gun is about $25,000.
You can't really establish an average price for a collectible car, because their condition varies so widely. You can buy a something like this:

that will require a full frame off restoration and will never be numbers matching for $10,000.
On the other hand, one of the 7 1970 Hemi 'Cuda convertibles will set you back about $2,500,000.
A top notch replica of a 1963 Shelby Cobra can easily run $150,000. A numbers matching original Shelby will be right at $2,000,000.
And you will have trouble finding anyone who will even guess a price for the one and only 1983 Corvette in existence.
In no valid comparison is your claim correct. Deal with it. You screwed up. Now move on.
