I do not agree that 409 cars have gone down in price. So much depends on the car.
The issues with the 63 409 that was posted and that I commented on are fairly minor, unless the color change is an issue to a buyer.
For example
Almost all 61-63 cars have the wrong factory master cylinder because you cannot buy a new correct original screw top master cylinder ( until just recently by Show Cars) - I have the correct master cylinders but install stainless sleeves so the old master cylinders do not leak
I have seen many 409 cars that do not have the correct 409 fan shroud - easy fix
The correct return line and fuel filter was probably not replaced during the 1963 engine rebuild
Very few 63 409 cars with a factory alternator have the correct deep groove pulley ( replacement alternators do not come with the correct pulley - same for the correct 409 generators on 1962’s 409 end plates and 409 pulleys not correct on replacement generators.
I do see a ballast resistor on the 63 starter wiring harness which was only used on factory 409 cars
As to the color change I see that on lots of restored cars, I did a color change on my friends frame off 62 SS 409 convertible frame restoration that I helped do …including changing the car from a 327 to a 409 correct restoration. This car sold 3 years ago in South Dakota for at least $95,000. I know the current owner would not sell it for less than $125,000
I did not see that the 63 exhaust manifolds are incorrect
The 409 flags and emblems are correct on the 63 posted
“I believe lots of guys restoring 409 cars do not know what is original” - from cars I have seen and reviewed items done on the restoration.
My frame off restored 62 impala Bench seat Hardtop 409 HP frame off restoration (993 points out of 1000 at Late Great Show) sold at Mecum Kissimmee for $68,000 4 years ago then sold by the dealer Ohio dealer who bought it for close to $75,000 -its now in Michigan
Just this month I helped a friend who looked for the last year for a 1961 Chevy Impala 2 door Hardtop with a 348 motor.
We reviewed at least 20 cars most over $75,000
We just reviewed the 1961 Impala frame off restoration car that he purchased from a Midwest dealer.
It was a true frame off restoration not rusty with new paint, new interior, restoration record book with pictures, bottom of car red oxide primer and with a 1963 409 - 2-4 barrel motor and 4 speed. He purchased it for $59,000 a fair price in my opinion for the quantity of the car.
I also have watched the a group of 3 frame off restored 1962 SS 409 convertibles sell all a Mecum reserve auctions in the last year for $140,000 to $170,000( comparing them to my 62 SS 409 convertible)
Do I think the prices for 409 cars are too expensive, yes I do but high quality cars bring good money.
