I bought this car used 90K miles after owning two other Caddy's as used cars before. The check engine light came on periodically and I had some stalling after a month. The cause of the check engine light was dismissed after multiple diagnostic tests as just "needing a tune up". After a year I replaced the fuel pump, a/c compressor, water pump, starter and had some sort of what seemed like a fuel line problem that no one could find. The Caddy dealer could not find the problem in two hours despite the check engine light. Suspension was like an old taxi after two years. I wouldn't buy another Caddy used.
Quick and smooth on the highway before the problems I just mentioned started.
Unreliable car. Once you have a problem you end up with multiple problems with these cars.
