I was basically scamed when I ordered Sienna from this dealership. I have signed papers and talked about one price. When I got the van on my bill of sale appeared price almost 3000$ higher. They have put in remote start and block heater without clearly pointing out it will be extra... None of the documents were copied or emailed to me for review after the order. My message here is 1. JUST BEWARE OF HOW SALESMEN PLAY WITH NOMBERS: ALWAYS MAKE SURE THE PRICE YOU DISCUSS IS "ALL IN OUT THE DOOR" 2. MAKE THEM SIGN ON THAT PRICE 3. TAKE COPIES OF EVERY PIECE OF PAPER YOU SIGN
