I've only had my new RL for three days, but, so far, I love it. I previously had an Acura TL, which I liked a lot, but wanted an AWD vehicle which was a little smoother on the road than the TL. I hesitated a bit on the RL because of both its cost and the exterior design, which I liked okay, but not as much as the TL. I test drove an Infiniti EX and G35X, a Toyota Highlander, Volvo S60 and S80 and looked at a number of other cars. I also drove the Acura RDX. The RL is the most enjoyable car I've ever driven and I recommend it fully. Buy it!
Smooth ride, responsive handling, beautiful and comfortable interior, great stereo, many standard features which are options on other vehicles.
I think the exterior could be slightly more stylish, but the car is such a dream to sit in and drive, that this is a minor issue.
