maybe I mis-understood a friend, but I thought he said that in the past he paid off a car loan early and paid a reduced settlement amount?? Does that sound way off....?
You took out a variable rate loan at 9.2%. Not the best rate but not a bad rate. You would pay around €1200 interest if you had this for 12 months. And maybe around €700 if you had it for 6 months.
Don't worry about it until you pay it off. When you get the final statement you can post the details here and we will check it for you.
