Casa Nissan of El Paso

Casa Nissan has the POOREST CUSTOMER SERVICE. I purchased a Nissan Sentra SL 2014 with LOW FUEL, OIL, and ANTIFREEZE. I had to take back the vehicle first thing the next day. The dealer failed to active the fuse box which would have indicated some of this issues. The car smelled burned which I brought up to the rep. and technician who took the car to get inspection, remove original wrappings, fueled, and washed. I took the vehicle to work two hours later which the seats still had the original tags and the passenger's visor still had the plastic wrapping after pickup. The car I purchased was $1000 over the dealer price tag. Which I brought up to the sales rep. at the time of purchase. I purchased the car at $23,866. The same vehicle at the Nissan website is listed at $21,495 and at Casa Nissan was listed $22,866 with their added add-ons. Either of the prices include the rebates that were offered at the time ($1000 cash back and $500 cash back which I did not get). The final price was $26,429 after taxes with an unnecessary vin etching fee. I only asked for GAP insurance. All this issues were brought up to the sales manager Mike Zuloaga in a 72 hour period. They refused to exchange the vehicle on the third day of purchased. According to the rep. Ivan Renteria, they had to get approval from a bank supervisor. Which isn't true because all they had to do was exchange the collateral. Mr. Renteria also mention that I had no credit and small accounts(I have a 743 credit score) and according to him they did me a favor by getting approved for the purchase. He was upset at the time because I had spoken to his sales manager prior to the conversation. P.S. I was recommended to this agency by a family member who had purchased a Nissan Altima three months prior to my purchase.
