56 fleetwood sixty special value?

Hello all I have a 1956 fleetwood sixty special 4dr that I am about to sell, it's been sitting a long time but it's in good shape.
The thing I am having a hard time figuring out is it has dual quads on it and from what I can find isn't normal, but it's all original so is this a rarity?
It ran when parked but it's sat for a very long time no rust holes anywhere I see body is straight, interior not in the best of shape all the parts are there even the air cleaner which is beautiful, one of the skirts is trashed but it has a replacement with it it also has a replacement windshield and lotsa of other misc spare parts.

I also have a few older Cadillac big blocks and tranny's and from wheel drive trans-axles any idea were a good place to sell these is? and what's an old 500 worth complete?

Dual Carter 4bbls were a factory option for '56. It is a nice selling feature but they are not really rare.
I would suggest to pick up a copy of Hemmings Motor News and take a look at what similar mid-'50's Cadillacs sell for Of course the Eldos, convertibles sell for more money, the coupes for less, and the 4 doors are the least valuable, for that year.

Of course the SoCal market may be a bit different than elsewhere but, based on your description, I think ask $6000, and take $5000, maybe????

thanx for the input that's around the price range i was thinking.

Good pics. That's about the condition I thought it would be in based on the age and your description. I think the asking price above is reasonable.
