1998 Cadillac Seville Reviews, Pricing & Specs
Write a review
Cadillac decided to make some more noticeable changes to the Seville for 1998. More specifically, the midsize sedan shrank from 204 down to 201 inches in length and widened from 60.9 to 62.7 inches. In addition, cargo space increased from 14.4 cubic feet to 15.7. The STS and SLS trims still have 4 doors and seat 5. Gas consumption ranges from 17 mpg in the city to 26 mpg on the highway. Standard features include air conditioning, power windows, power door locks, leather seats, power seats, cd player, and ABS brakes. The SLS uses a 4.6 L, 275 hp V8 engine while the sportier STS uses a 4.6 L, 300 hp version. Passenger volume increased from 102.3 cubic feet to 104.1. Despite the changes, consumers still have issues with oil leakage and consumption, as well as overall maintenance issues. Commentators assert that these durability concerns kept Cadillac from making good on its proclamation that the 1998 Seville would reclaim the title of best sedan on the market. Without a significant upgrade in parts, the Seville lineup confirms the old adage that beauty is only skin-deep.

I like this cars features. Hate the motor it’s been nothing but problems.. Honestly the car rides smooth is easy to keep cool with big windows and has heated seats all the way around. It’s a really nice car but the northstar engines are junk. That being said it needs a new motor and transJun 09, 2023

I spent $3400 (CDN) for a Bose stereo and it came with a really nice car to carry it around in.
300HP, 4cam, 32valve Northstar V8. Performance Algorithm Shifting. Stabilitrak (Bonus: Any car that tries to save it's own ass is also trying to save mine (Which is nice, as I'm probably the one that caused the problem)). Continuously Variable Road-Sensing Suspension. Rain Sensor Wipers. The aforementioned Bose DSP 8 Speaker (1 is a sub) CD/Cassette/6disc Changer in console w/three 6disc cartridges (I had two magazines left-over from my Lansdowne UCD collection (+ two brand-new Cadillac RKE fobs #s 1 & 2)). (My Sansa e280 runs through a cassette adapter, 1000+ songs)
Twelve years old, 245000km (150000mi +/-) and it still feels as good as a new Buick I had as a loaner recently. (Plus it gets better mileage than the Tahoe... This car ROCKS on a longish commute like mine.) The only factory option this car is missing is the adaptive seats, (seats adjust themselves, every four minutes, to changes in your position on the seat, and it back massages too), I don't miss them as I didn't like them when I played with them at the dealership. (Thank-you Internet... There were, apparently, only fifteen cars built with this exact build spec (Black/black and same options)).
WARNING!!! Do NOT buy one of these if you don't already invite your GM technician to Christmas dinner. (Or speak fluent Cadillac or own a GM tech tool. I, thankfully, can say "yes" to both. (All three, actually. :D))Jun 23, 2010

This car is an all-around excellent car. It's not a world beater -- as an SLS, it cuts out at 115 mph, and it's somewhat wallowy in the turns. But it's a quintessential Cadillac: quiet and comfortable around town, powerful without being obnoxious, and an awesome highway machine. The Northstar is a very torquey engine and whisper quiet until you stomp on it, when the car just goes. The transmission is bulletproof and works just fine, she gets decent mileage on the road (I've recorded 32 on a completely highway (but below 65 mph) drive, but as low as 17 in town), looks like a cruise missile, is awesome in the snow, and has never given me major problems. These cars are getting older and cheaper, and their original owners are finally selling them and trading up, which means that you can get a fantastic and luxurious car rather cheaply! Treat yourself to the best American luxury. Purchase a Cadillac!Feb 23, 2010

Cadillac electrical issue?
1998 Cadillac Seville Sts. Alternator on the car went bad, Had the alternator replaced, then I got a voltage reading of 16.5 ( too high ) I took the car back to the mechanic and They did a rebuild on the alternator... Now. For two years 98/99 They put a Thermistor on the hot wire from the battery ( located under the back seat ) I unplugged it not knowing what it was and the voltage went down, however the power is all over the place now. Shifts between 13.5 and 15.5. Randomly things stop working I.e rear defrost, gas gauge, sunroof, power locks, gas cap, trunk while others still work... power windows, front defrost dash lights. Thought maybe this was a fuse issue? So Narrowing it down to Voltage regulator, Thermistor, random bad wire. Everyone seems stumped over this. One person said to attach a 1600 ohm resistor to where the thermistor was and that would correct the problem, I haven't tried this yet, don't even know how to go about connecting the resistor.
