My opinion of the 1990 Lincoln Continental, based on my own sordid experience, would be: It has been one of the worst cars ever from a reliability/maintainability/mechanical standpoint. I have had to replaced almost every major system. The only major component that has not failed is the forward portion of the transmission. The plastic interior molding flakes silver chips constantly and has for years. The sun roof leaks, the engine cuts off for unknown reasons during the spring and summer, the A/C/Heater is stuck permanently on "on", etc.,
I have been more than happy with my car.. to the point that although I have had no major repair needed the entire time I've owned it, I would not hesitate to have those repairs done.. this has been one of the best cars I've owned..
My first experience with buying a used luxury car with 80k miles. Lots of expensive problems with brakes, faulty engine head bolts but I really liked the way it rode and drove. Finally sold it at 125k miles when it needed new air shocks, at that time only available from mfg. at more than what the car was worth! Even then, probably would have done it but transmission had a weird slipping problem going around corners. This was essentially built on the Taurus platform and with improvements to the items mentioned is what the Taurus should have become in my opinion.
The lincoln continental is a very fun car to drive , but there are some issues to deal with like the air ride system and the factory sound system, transmissions. I've owned three and all Ihad trouble with was the air ride, but if I was to tell someone to get one and drive one for themselves is the only way to experience them.
