What is usury? For an interest rate/ loan to be considered usury, how much does it need to be?

Question

If the blue book value of a car is 2,000 and the "other" expenses for the car bring it to around $10,000 , how can you determine in a court of law whether or not this is usury?

Answer 1

Usury rates are set by the various states.  It's really very complicated, and the rules apply differently from one type of loan to another.  Here's a pretty simple, relative clear explanation:  http://www.lectlaw.com/files/ban02.htm

Other expenses wouldn't be covered under usury laws, because they wouldn't be part of the interest rate.  The mark up can be pretty much whatever the market will bear.  They may have done some work they want to be compensated for, or whatever else a dealer may add into the price of a car, but no matter how ridiculous it may seem, it's not usury.
