Feature lists reflect cumulative standard equipment for each trim, a trim includes everything from lower trims plus its own additions. The monthly figure is the trim price over 60 months at an assumed 7% markup with $0 down, an estimate for financing through the brand's own financial company. That markup is profit on a cost-plus sale, not the Loan Excess, because the financier owns the car it sells. The 7% is an assumption for illustration, not a rate anyone is quoted.
