We leased our IS250AWD in December 2008. The navigation system is superb, we prefer it over the navigation in our Acura TSX because it signals a beep tone when turn a is approached so there's no confusion. One significant drawback for this model are the Low- Profile tires.We live in the Northeast in a larger City where pot-holes are common. In the first seven weeks we had to replace three tires due to bubbles on their side (irreparable damage, not under warranty). We estimate that over a three year lease period we replaced ca. a dozen tires on this model. Low profile tires might be suitable for a smooth rural road in the south but are not suitable for towns like Boston, N.Y. or Philly.

Unless Lexus offers this model with Regular (High-profile) tires they will loose more and more drivers in larger towns where pot-holes and rough road surfaces are the norm.
