I think it was for when the car dealer arranged HP for you but didn’t tell you they were getting a kickback from the loan company. I took out a £4k loan for the car we are getting in September (only to trigger a £2k deposit contribution from the manufacturer). I’m going to pay it off in month 2 but in the bumph it told me that the dealer was getting £200 commission for arranging the loan. Funny thing is, if I didn’t pay it off early and paid it over 2 years, the total interest paid on that loan would be £202! Hardly seems worth the manufacturers time to earn £2. It’s probably set up to earn from those that take out a huge sum for the car.
