Replaced our LR3 with a 2008 X5 3.0si. Test drove Acura MDX, Mercedes GL and R classes, Mazda CX9, Toyota Highlander and Audi Q7 before making our purchase decision. 3.0 engine has more than sufficient power. It is actually quicker than my 2002 325i.
Transmission is super smooth. Interior is gorgeous. Handling is best in class.
Redesign the rain gutters. Open the doors when the car is wet and water falls onto the seats. 3rd row seating is very tight and only suitable for occasional use by very small occupants.
