I am going to rebuild a 1971 Cutlass SX 455. My question is how much value loss is estimated if I changed the original color and the original interior color?

 

If not completely returned to a "new off the line car" then not much at all if any.
It's your car right now do what YOU like! Not what you expect for a return in the future. As far as color if original paint that needs absolutely nothing and I doubt that as you say it already needs to be rebuilt. Keep it. Same goes for the interior. If not anyone after you sell it can change it back or whatever color they chose... If you plan on flipping the car then I would stay with the original color.

 

It also depends on the original color. If it is *** brown, then maybe a change will improve it.

 

Also depends on what you change it too.
if you stick to the factory color chart you should be fine.

 

The car is " Palm Green " now and interior is also green. Son in law wants to change colors and I told him I think the value would drop from being original.
Also have a 1970 numbers matching GTO that is Gold with the brown interior that he wants to change.


Both need paint and interiors


I think we should keep original, just don't know percentage wise how much less they would bring if not original.

 

If you dont plan on selling the cars then i'd do what makes you happy. A car, house or any possession is technically worth nothing until the moment you sell it. Anything before that is an estimate.

I dont plan on ever selling my cutlass, so it's in original factory #81 Bamboo. But thats the way i like it.

 

I would say plan on selling value cause at my age you never know !

 

That's cool, i'd keep it original colour then. But if i were to go out and buy a white or green or red 4-4-2, i'd expect it to match the trim tag if the seller wanted me to pay top dollar.

 

I am a keep it original guy. To me, the value would drop by the cost it would take to make it correct plus $1000 for my time.

I had my W-30 repainted going from Sebring Yellow to Maditor Red in the mid 80s. I'm going to redo the car next year, it will go back to Sebring Yellow.

 

Paint is paint, not like you're going to resto-mod the cars. There are a couple of things I agree with that have been said.......made yourself happy, stick with year code colors. Before changing it I would check production numbers for your colors. Sometime the rare colors increases cars values. From my experience I would sure check out your paint guy too and check references. All that said, I like keeping the base color factory.

 

The reality is that neither OCA nor AACA deduct any points for paint and interior that are changed to another factory-available color appropriate for that year. In particular, changing from green to a more popular color will likely increase value, unless this is a stone-stock original rare car like a W-30.

It is a stone stock SX455, not many made in 1971.

 

in this case altering the original paint code will reduce the cars value quite a bit... if it were me buying i wouldnt even consider it if it were painted another color

 

I always say if you are building the car for sale then stay original. If you are building the car to enjoy, them make it what you want. Don't worry about the value. you will spend way more than you orignally planned on it anyway.

Just enjoy it for sure
