So trying to find the right trim package and color the buyer wants is difficult. I just checked the main Utah Toyota dealers for Sequoias and they have very few in stock.
So if the buyer is after a particular model they may have trouble finding it. Since the Sequoias are in short supply, dealers are trying to add the "market adjustment." However, some dealers don't do that so the buyer has to shop around on the internet and try to find the right car for the lowest price. It is possible, just have to do the work.
