We just purchased a Lexus for my wife and we both love it. I've always been a fan of the Infiniti brand more so than the Lexus. But the customer service at Lexus is unbelievable. Here lies my dilemna...I want to trade in my Nissan Armada on a luxury SUV next year. I like the Lexus for it's vehicle and customer service, but the price is too high. I'm afraid the customer service for Infiniti won't be up to par and I'm scared the QX56 will ride too much like a truck (like my Armada does). The FX50 is in the equation simply from a sporting standpoint.

So taking into consideration the above mentioned items, and the fact that I will be purchasing in Jan 2010 or so, which would you choose and why: A certified used 2008 Lexus LX570, a certified used 2009 Infiniti QX56 or a certified used 2009 FX50?
