I bought this car, tongue-in-cheek, 3 years old in 2000. My daughter had just totaled my Honda Accord, I got her her own Sable (for punishment) and bought this Acura 3.5RL for myself. It turned out to be the best used car I've ever had. Cushy ride, great reliability, superb design, plenty of power, decent mileage. Still going very strong in the hands of same daughter. I miss it. My 2004 RL is great, but not as comfortable.
Very reliable, very comfortable, excellent design - dashboard layout, controls, trunk space, even a ski- storage port.
Better gas mileage (mileage is good but not great), use regular gas, not premium. Really not much to improve - this is a great car in so many ways that you don't discover till you own and drive it.
