cost + reliability + SUV + worryfree = 4Runner. Think about it, of course X5 will give a difference feeling when driving. But to financial sense and functionality 4Runner is the best choice. I have no repair bill on my 03 4Runner up until now, and the 03 X5 gave me 10 repair bills after the warranty expired that includes windows regulator, door actuator, brakes, cv boots, battery, water pump, thermo sensor, thermostats housing, oxygen sensors. You name it. With the 4Runner, all i did was oil changes.
