The RL is my second Acura. I bought a CL Type-S in 2001, and was very pleased with its performance, reliability and fun-to-drive factor. The RL is awesome. With 3500 miles, everything has worked as advertised. It's roomy, plenty of power, every gadget imaginable... great technology, and it all works.
Believe it or not, my favorite feature is the XM radio... not even an ACURA feature!!! Also like the navigation, Bluetooth phone, voice commands, and power everything, including rear sunshade.
More levels of front-passenger seat adjustments would be nice. The rear defroster doesn't warm up quickly or hot enough. There is a slight lag upon acceleration, a bit disappointing for a 50K car... overall performance, however, is strong.
