I bought my Regal LS with 17,000 miles on it - previously owned by an elderly couple that rarely drove it very far. Since then I have put 100,000 mostly hwy miles on it and had only two costly repairs: replace valve gaskets @104,000 and replace starter moter @111,000. I try to keep my cars forever and 'over maintain' them, but 10 years is about the limit for a 90s GM car, unfortunately. Little things start adding up: sealed headlights are starting to fog up as moisture gets into them, trunk seals are failing somewhere letting rain in, plastic exterior trim pieces are starting to show their age and lack of quality. Too bad - I think the engine will run forever.
What I like is the responsive wheel and great gas mileage (I can get 30mpg highway - this is not the turbo- charged model).
What I don't like is the plastic interior (the cup holder broke a long time ago), and the lack of lower back support in the seats.
