This is something that I still don't understand.
Say, I finance a car:
0 down, 60 months, 1.8%
the payments are 500/month tax-in
1. If I want to buy the car at the 20th month, do I pay (500*40 - interest) + some sort of penalty?
2. If I pay 10,000 at the 20th month. What happens to the remaining payments?
