The ride, handling, quietness and finesse of the Cadillac Seville are amazing. This is a quality vehicle. Use proper care and maintenance and it will treat you right. I have never had a problem with it.
I loved this car but it gave me alot of trouble. This was my first car bought for 2500 with 93000 miles. I went over a year with radiator fan, winshield wipers, and heat in Minnesota. One day it would run like a dream the next it would barely get to 70. I really didn't want to get rid of it but needed something more reliable to go to college with. List of things that didnt work: front struts, ac, heater core, heater fan, interior lights and gauges flicker, went through three batteries one started on fire, tranny slipped, 6 fuel injectors went out, remote trunk release, radiator fan so i couldn't idle more then 3 min, windshield wiper arm broke, rear window defroster, very uneven tire wear.
Just purchased this car from it's original owner who kept it garaged and never driven in rain or snow. Picked it up for a song. $900. I thought I hit the lottery. The body is perfect with a couple small dings and scratches. But from sitting so long the pay off was not at all what I expected. Only 49K and had to replace the tranny costing $1800. Fixed the Cruise, blinker, A/C, Rear shocks are next and heater core is believed to be clogged. The performance and ride are tight and squeak free. She gets up and goes! I thought I was just going to do a little touch up work on the dings and all my money went into fixing the quirks. :(
The 1990 STS continues Cadillac's commitment to excellence. Yet it departs from the "old-fogie" connotation of the Cadillac name. It has a spacious and comfortable interior, along with a sporty design on the outside. It drives very smoothly, and handles well. My car just turned 170,000 miles, and is still running strong. This is testament to the value of preventative maintnance, and the quality in manufacturing of Cadillac and GM automobiles.
