I've only had for a year -- purchased used with 60000 miles on it -- mint condition. No problems so far -- runs well in winter and summer (live in cold climate). Very smooth ride -- brakes well -- and handling is surprising for the size. Very nice on highway. Previous car was an Accord -- for the money I get a lot more features -- and the used RL's are not much more money then the V6 Accords for same year. Highly recommended.
Bose stereo, seating position for driver (I'm 6'4" tall), quiet, air conditioning, solid ride, build quality.
As everyone says it could use more power -- but I like the balance with fuel economy.
