I test drove them both. The LR4 is a nice ride and was almost the way I went but I just couldn't warm up to the rear end styling with its plate holder to the left and the rear glass lower on the one side. It is however a far more appealing vehicle than the LR3 and costs about $10K less than the RRS. I thought driver room was as good or better. One thing I did notice is the LR4 also has more wind noise at highway speeds than the RRS. At the end of the day, I think the RRS was the better choice for me.....
