I compared cars for 9 months before deciding on the RX350. Last two in the running were the Acura MDX and the Lexus. In our case for a family of three (one still in a carseat), the Lexus was great, however, if you are having more than one child, you might want to consider something a little larger like the MDX. I've had many families tell me that once they added the second child, the Lexus didn't feel big enough for them. One other determining factor for me was the ride of the Lexus. It was much easier to drive. Smoother feel, less work. The Acura has a much more "sportier" drive but it still road wonderfully. It's all dependent upon what you're looking for. If my husband was going to be driving this car, he'd of gotten the Acura. With me driving, the Lexus ride won.
