From looking at thousands of cars over the years and buying many, I found that many dealers make mistakes all the time. I have seen models listed differently than what they actually were. When looking at it I would tell them it was not the model listed and it was this model because of so and so. They would just say it's our mistake.
One story is back in early 2007 I saved my father $7000 on a 2006 F-150 supercrew Lariat 4x4 truck with 12,000 miles on it. I knew the listed price $24,999 was a typo but when I called and asked about it they told me it was the correct price. Told my father to jump on it and he went in to make the deal after looking it over. When he was about to sign, they told him it was a mistake and that was the price for the 2005 XLT with 30,000 miles. Furious when I heard what happened, I called and spoke with the general manager. He told me he was not informed about the incident and would get back with me. He called back an hour later saying what I told him was verified through the employees and said because of that, they would sell the truck at that price of my father still wanted it. The dealer had bought the truck on trade-in for $28,000 and was suppose to sell for $32,000.
This Pathfinder is an SE by the cloth interior, the manual 4x4 shifter, and the SE emblem right on the liftgate. The details listed are probably just a copy and paste info when creating the ad when the employee did not know the difference between and SE and LE model.
