Imagine yourself cruising in this Silver 1957 Cadillac Series Sixty-Two Convertible. The '57 was arguably one of the best looking fifties Cadillac and a real credit to Harley Earl and his team.
Power comes from the original 365 cubic inch V8 engine connected to a Hydra-Matic drive automatic transmission.

You'll notice the vertical moldings with 7 horizontal windsplits just forward of the rear wheel openings - these are only found on the 62 series.
All Cadillacs for '57 a new tubular-center X frame chassis, that allowed the cars to sit lower, and power brakes and steering were standard. Power windows were standard in the Convertible as was a two-way power seat. The original buyer of this car opted to upgrade to six-way power seats.

1957 saw new front end styling with rubber bumper tips and dual parking laps found in the lower section of the bumper. A dual taillight theme were found across the range. Pointed shark style fins were now seen on the rear fenders. Previously these were only seen on the Eldorado Seville for 1956.

You are incorrect in that the Coupe de Ville and Sedan de Ville had those 7 bar windsplits, along with the 62 Series. The de Villes had script on the front fender that read either sedan or coupe de ville while the 62 series just had the word Cadillac.
Hi Gary
it’s correct that the de Villes had a script on the front fenders. However, the Coupe de Ville and Sedan de Ville were part of the 62 series with style numbers 6237DX and 6239DX respectively.
Here’s a shot from the 1957 Cadillac sales brochure

I have a brochure that shows them as seperate cars, but I can’t post it here. Also, that emblem was used on all models except the Eldorado’s. The 62 series was cheaper I believe. I had a 58 sedan de ville and a 58 62 series sedan, the 62 had vinyl seats and the sedan de ville had leather. Plus another trim molding difference, but not on the 57. I can send you the brochure page I have if you’d like, just need an address.
