I like that Cadillac Eldorado! In the Cadillacs I like the hardtop better than the rag top. The condition of the chrome is really important as the cost of chrome has skyrocketed. It would have to have air ride though

I either like car lifted or lowered.
Mark, "General Motors (GM) produced 704 Cadillac Eldorado Broughams between 1957 and 1958. This limited-edition, hand-built car was a status symbol for the wealthy and famous." Ford's hand built 1956-7 Lincoln Mark II at $10,000, and GM's 1957-8 Cadillac Eldorado Broughham at $13,074 both lost money on every one they sold.
It has a brushed stainless steel roof, forged aluminum wheels and a 325 [or 335] HP, 10:1 compression ratio with dual 4-barrel [or tri-power] carburetors. Like the Lincoln 4-doors with rear suicide doors, there's a pillar in the middle but the Caddy's is a bit shorter. No way they could build a convertible 4-door on that X-frame chassis. To me, the front and rear are awesome. But so is the side when the windows are up, down and the doors open. It had so many features that were ahead of their time, but some, like the power vent windows, cigarette box and cocktail cups are unique to its time.

This one was supposedly purchased by Coco Channel and is a 54,000 mile survivor in Arizona. It's a '58 so it has tri-power instead of the dual 4-barrels of the '57. Like you said, the chrome trim is critical and the description of the car indicates a couple of emblems were not put on the car during construction. It still has the cosmetic and cocktail cups accessories in the glove box. At some point in its life, the air suspension was replaced with coil springs but replacement parts are still available.

Unless it has been swapped out like this one, all of these Cadillac Eldorado Broughams came with air ride as standard equipment but you'd have to update the controls to be able to adjust the ride height to anything higher or lower than standard. It automatically adjusted the ride height regardless of the load the car was carrying. Also, the engine driven air pump is pretty big.
GM actually offered air ride as an option on all its 1958 passenger cars. I rode in a '58 Bel Air that had that feature. Six of us piled into the car and it lifted itself back up as soon as the engine started. When the system developed a leak, the car would slowly drop down onto the bump stops when parked. Ford put air ride on the 1988 Lincoln Continental Signature Series. A few years later I'd spot the occasional one driving down the road on its bump stops.
Found a press kit for the Cadillac from back in the day:
