Faults:

Steering rack, this needs to be replaced, not a cheap job.

Mystery Over-heating problem.

Brake discs and pads wear quickly.

Strange, random electrical quirks that sort themselves.

Headlights go out of line easily.

Uses oil, but then they all do.

We are looking at a bill of around £4000 to get this car right.

General Comments:

A very, very fast car, for a big heavy sedan, it will eat practically everything out there, but then cruise silently all day at 100mph on the motorway.

It also handles very neatly and grips forever, you would expect less front end traction, but it just grips even from a dead stop with the throttle wide open.

The brakes are very good too when they are in good condition, the ABS, traction control and Stabilitrak all work very well.

The BOSE sound system is awesome, really fantastic sound, with a radio, tape, 6 disc changer and MiniDisc.

Crimson pearl paint is well worth the upgrade cost, it looks gorgeous in the sunlight.

This car will cost a lot of money to run, but if you want to run a car like this, you have got to live with it, service it frequently and treat it right, ours has not had all the care it needs and thus is costing money to fix, but if you take care of it, I can see it lasting decades.

We will definately have another Cadillac.

My STS had tire problems similar to those mentioned by others. The Original Goodyear Eagle LS tires were nearly impossible to keep balanced and wore out after 32,000 miles. I replaced the original set of tires with another set of the same tires and experienced the same problem, replacing them with Michelin MXV4 tires at 64,000 miles. The Michelins have performed flawlessly. They provide a smoother, quieter ride and show no problems maintaining balance.

Concerning the burning of oil, my experience has been that I need to add one quart every 4-5 thousand miles. Previously, I owned a Corvette and had the same problem. I believe that kind of problem is enherent in such a high powered engine. I drive the car hard and fast, enjoying the benefits of this fine machine.

This is no $70K automobile. I paid less than $50K, new and loaded.

General Comments:

This is a well-tuned machine that performs as expected.

Absolutely nothing.

My 1999 Seville STS is a dream car to drive, ride in, and look at. Cadillac got it right with this model of Seville. The V8 Northstar engine is full of power and can easily get the car to cruising speed in a matter of very quiet, smooth seconds. Or if you prefer to step down on the gas prepare to get your head jerked back and burn some rubber from your tires as this baby goes from 0 - 60 in a matter of eye blinking seconds.

I really don't have anything bad to say about this car. It's a symbol of American pride and of great American cars gone by.
