I have a 4 cyl. 2006 LTD Rav4. Overall very pleased with the car, but it has a serious safety issued relating to the ECU. I don't know that much about it, something to do with an electronic throttle or some such thing. Anyway, if you check other forums you'll see more and more complaints of a serious Lag or Hesitation normally 2 seconds or so when trying to either merge, or accelerate from a slow speed. I've nearly been rear ended on 3 occassions. I'm 58 so i know how to drive, but when you push on an accelerator to merge etc. it should pick up speed, not get lost in some strange mode. Toyota claims this is normal. understand Camry has same issue (not sure if with 4 cyl. or what) but possible ECU solution or computer change etc. Anyway, for this one issue alone i cannot recommend the Rav4. Shame cause it overall is a great vehicle.
