Looked at ML350, Q5, MDX, RX350 and X5. This vehicle was head and shoulders above the ML350. Each of the others had its strong points; but my wife chose the XC90 because she liked it best (it had the best overall visibility). We've had it for almost 4 months now and have had absolutely no problems. The fuel mileage is lousy; but competitive with most of the others--14 in town and 21 on the road. It does use regular while the others require premium. The fact that the XC-90 is the least expensive of the bunch is real bonus.
