Our daughter got a discount for good grades and for taking the course. All in all, about 15% discount.
Our insurance went from $875 each 6 months (2 cars) to $2000 each 6 months (3 cars) with no tickets, etc. I know our insurance is higher because we all drive high end Mercedes (07,08,10). Our deductibles are $1000.
We don't require her to pay for gas or insurance. She does have to keep her car very clean, it is in perfect condition with no knicks, etc. She does have 3 families we babysits for regularly and gets paid well. She buys her clothes, etc.
Now, if her grades were to plummet, and if we need to discipline, we take the keys to the car, she does not drive to school or anywhere else.
Just because she is well provided does not make her spoiled as I have heard people say. She appreciates the fact that her parents take responsibility for her and provide well. There are some jealous kids at school. Maybe if they held up their end of the bargin of working and maintaining good grades instead of feeding envy, they'd have a good car (as well as other things) as well.
When I bought my first car, I had to pay for all expenses and I had 3 jobs through college.
