Purchased a used RX350. Was told it was never in an accident. Blind spot never worked and upon further inspection i found the vehicle had been in an accident and wasnt repaired. They just painted over the bumper but left the damages to tbe quarter panel and BSM untouched. This dealership has not taken resposibiliy leaving me with a broken vehicle. They are not honest. Stay away!!
