Like animal fries at In-n-Out, the $35k is not shown on the website. You have to call and ask for it specifically.
Or if you prefer you can order the $39.5k one and call up service and get them to change the settings, and then they'll send you a refund of $4,500.
Does this all sound strange? Sure, but I guess they have their reasons for doing it, which seem to be mainly to keep the menu simple and steer people toward the best value, because the $39.5k car is a better value than the $35k car.
