Lexus2004

2nd disappointment with the salesperson that sold me my 2011 RX 350 in November 2012 from our local Lexus dealership. My husband and I was told when I purchased the RX 350, by the salesperson, that the car used regular gas. Yesterday I was informed by the gas station attendent, who was pumping my gas, that the gas cap read to use premium gas. Do I have to use premium gas? What recourse do I have with the dealership regarding incorrect information given by their salesperson? Thank you..

Interested in purchasing winter mats, in black, for my 2011 RX 350.. Does anyone know the cost for these mats? Thank you
