Car Finance - redemption figure

Hi,

We are looking at selling our car and buying an older one. I was just wondering what the settlement figure would be. Is the interest added as you go along, or is all the interest added on upfront.

I dont want to sell at a knock down price, and then realise there is a couple of grand added on regardless.

It is a car finance agreement with TSB.

Kind Regards
Caz

Sorry, just seen a similar post so have read the replies, have emailed them to check before I try and sell.

Dont want to sell and then discover Im still left owing money and then not even an old banger to bring the kids to school. Ahhh.

Cheers
