I was interested in the Costco Auto buying program, after entering my info in the Costco site, this dealer was one of the choices. I was interested in a 4runner and I am writing this negative review because the addendum sticker next the to the window sticker rose the sticker price about $7-8K. Listing items like nitrogen filled tires for $399? The air we breathe has nitrogen in it and the best was dealer mark up, about $6500 without any itemization. The salesman mentioned that he could get me a great deal for $7k off from the $48K in the addendum sticker, do the math and the price is $2k above the sticker, this is what passes for a "deal" these days. I opted to buy a lightly used 4runner Off Road edition from a different dealer, paid below KBB value, the best thing to evade that addendum sticker.
