On the slider which compares selling with Instamotor vs. trading with a dealership, I think you should consider changing "You earn" with "You save." It was confusing to me exactly what it represented.

Also, not sure if it matters too much, but generally framing things as "not-losing" is better than framing something as a gain.[1]
