After a down period in the mid '80's, the Cadillac Seville luxury midsize sedan continued its comeback with an upgraded engine and sleeker styling to kick off the new decade. The 4.5 L V8 engine now boasted 180 hp and came with 4 speed automatic. The new model also used sequential fuel injection for improved power and emissions. The 1990 Seville has two trims: the STS and STD. The STS represented Cadillac's attempt to make the Seville appeal to a younger crowd with a sportier exterior, better handling, and faster acceleration. Gas consumption runs from 16 mpg in the city to 25 mpg on the highway. The Seville seats 5 and has 4 doors. Standard features include air conditioning, power windows, and power door locks. If you want, you can also get a sunroof, leather seats, and ABS brakes. Overall, drivers still enjoy their 1990 Sevilles. Several devoted owners report putting over 200,000 miles on their car with almost no major problems. If you don't need the most advanced features, the 1990 Cadillac Seville still provides plenty of bang for your buck.
