1980 Cadillac Seville 6.0, 368-FI from North America
Guaranteed future collectible
I replaced the rear air shocks and the Throttle Position Sensor. I also replaced the front filler panels.
The 1980 Seville is one of the best Cadillacs. It looks like a million dollars and I got a thumbs up from a Silver Cloud driver the first week I got it.
The interior is a bit snug in back, but is luxuriously appointed, with more leather than most of its contemporaries, thick carpeting and a telescoping steering wheel.
A/C is very cold, as the Seville had the highest capacity unit in its year. R12 should be used to recharge.
Fit and finish was excellent, but beware of repaints over the original lacquer, as most modern paints are incompatible and can alligator.
The 368 Fuel Injected Engine is the only way to go with this car. Don't be fooled by the 145 hp rating, it has a lot of performance (0-60 in 8-9 second range) and is the smoothest, quietest engine made by Cadillac.
The 368 is the final generation of the Cadillac big block. It will get 20mpg highway at 75mph. Any other engine in this car is to be avoided.
The THM-325 trans is fairly durable and much better than the 82-25 325-4L, which was known for more frequent rebuilds.
The Seville is slightly firmer riding than larger Cadillacs, but it handles well, thanks to independent rear suspension. There is no torque steer and the highway stability is amazing, and it stops well, thanks to 4-wheel discs.
This car will also diagnose its own problems. The climate control unit will generate trouble codes from any system that has a sensor. The only issue with this car is availability of sensors for the FI system. They are discontinued and can be hard to find.
Would you buy another car from this manufacturer? Yes

Are you crazy? The 1980 Seville is an oxcart compared to the 2001 - 2004 Sevilles!

Thanks for posting this review. 1980 models are quite rare these days and are most desirable among collectors. Newer models may be more advanced, but they lack the style, elegance, and durability of the 1980 model. It's surely not an oxcart compared to any vehicle; especially newer disposable Sevilles. Enjoy your car. You have one of the great ones.
