Although the RX330 has some improvements, there have been some steps backwards in my opinion. The car is much noisier than the RX300, particularly noticeable at speeds over 50. Highway noise is NOT muted as in other Lexus models, wind noise is a constant. Transmission shifting from a start is laborious and loud. The Mark Lev radio is nothing special and its volume controls are make it hard to find a volume that you can keep it on. The radio lite is too bright. The back-up camera is weak: at night the screen "whites out",and there is no useful depth perception. The adaptive headlights gyrate and flit around constantly as you go up and down hills and are of dubious benefit and value.
Very comfortable seats. Elegant interior. Reputation for reliability and low cost ownership. Handles adroitly for an SUV, and better than many cars. Easy to drive. Excellent brakes. Good, yet complex navigation system. Very useful floor console w/good cupholders and cubby storage.
Cabin must be quieter; wind & road noise is excessive. Back-up camera needs distance marking indicators, better quality camera for night use. More intuitive,navigation system. Better ext.colors with lighter int.color choices. Need bigger rear window that opens. Redesign the tail lites! Gas mileage!
