Automatic Climate Control, cruise control, power seats & windows standard
Notable Changes:
Cadillac refined the digital dash electronics in 1985, making it slightly more reliable.

Powertrain & Chassis

Engine: Updated 4100 HT-4100 V8 as noted but the cast aluminum finned valve covers (135 hp)—still underpowered but reliable with proper care.
Transmission: 4-speed automatic overdrive (Turbo-Hydramatic 325-4L).
Ride: Cadillac’s Computer Command Ride standard again.

Rarity & Collector Status

The 1985s are rarer than 1984s, with fewer built and fewer survivors today.
Being the final year of production makes them especially collectible.
Cars with rare color combos or low mileage are highly prized.

1985 Unique Notes

Final-Year Production: Marked the end of Eldorado convertibles until the introduction of the Allanté in 1987.
Improved Quality: ASC worked out some early conversion quirks from 1984, making the 1985s generally better assembled.
