Tardy to the party today…will post again in the evening.
Talked to a coworker about buying cars yesterday. He expressed a lot of frustration with the way dealers manipulate financing to make more money off you:
1) making low offers for trade-in (or increasing sticker price of the car with a trade-in)
2) changing the APR
3) changing the length of the loan
4) upselling expensive cars
Could be a good real-world problem for financial math, especially since some 12th graders are interested in saving up for cars.
