This is the second RX we have had. Previously we had the 2001 and were so happy with it that we traded it in for the 2004 model. We have had no significant mechanical problems with the car to date. Would highly recommend the RX - fun to drive and nice to look at.
By far, the best feature is the automatic rear door. It makes loading and unloading so much easier.
The location of the gas door button is somewhat hidden. Also, the car is equipped with headlight washers, but no wipers. The spray goes all the way over the hood and makes a mess. Not a necessary feature.
