Go with the 4Runner. I own both X5 and 4runner right now same year 2003. I never have to take the 4Runner in for repair since I bought it brandnew in 03. I have the V8 so it accelarate faster than my X5. I am more pleased with the 4Runner than my X5 since it never gives me surprise repair bill. It has more room, good for homedepot trip. Can go anywhere including thick heavy snow we had couple of years ago, it just blast right through. As the warranty of my X5 expired, darn, It constantly gives me repair bills. My wife doesn't even want to trade the 4Runner with my X5. She is afraid that the X would just DIE on her. She is more confident with the 4Runner. Dont get me wrong, I love my X more than any vehicle I own or have owned. But to be realistic, 4Runner does the job right for an SUV.
