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.

General Comments:

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.

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.

General Comments:

Excellent previously owned car the purchase of which cost me $ 6000 back in 1997

I drove it all around Europe (Italy, France, Germany, Austria, Hungary, Croatia and Switzerland) without major troubles. Never let me down on the roadside !

I kept a speed of 75 miles per hour on freeways.

I did 18 miles per gallon (average) or less

Its one of the most comfortable cars in the world.

Highly appreciated by very old passengers (and myself, the sole driver): very very quiet, very soft and smooth running as if you were on a magic carpet...

A real danger to mention: it's so comfortable that you forget you are driving a very heavy car and you may feel drowsy after a few hours driving on the highway, whatever music you may be listening to.

Highly conspicuous vehicle and not recommended if you intend to rob the next downtown bank...

Not very popular with (underpaid) French customs officers at the border who still consider it, wrongly, as a status symbol and can get fussy.

One regret: I wish I could have bought it in 1980 when it was brand new !

I own one of these cars (one of four cars). It is now 24 yrs old and I have to replace none of these parts. Often the 'mechanic' is a cars worst enemy. As an ex mechanic, I have done most of my own repairs according to the manufactures shop manuals and can see why some item might get replaced because of misdiagnosis. One owner of one of these variable displacement engines commented that the had trouble adjusting rear disc brakes. Well, this car is different than others. You must take off nut, remove, adjustment lever, (Hexagon cut into lever fits over hex head on cam) reposition lever, and reinstall. Simple fix, if you know why you are experiencing problems. I think that this is one car that should NEVER be fooled around with by a back yard mechanic! It is unique in many ways. I have spent almost nothing on this car except gas and oil, car washings by hand and it has 77,000 miles on it. Still looks like new, drive like new, and rides better than most new cars! Just gotta know the mechanics of this vehicle!
