I going up on thursday to finalise the finance - presumably if you end early (and pay it off) = less interest charges ?
And on the other hand, usually an "early repayment penalty fee" added to it also. Depending on the loan agreement, sometimes you can get around this by overpaying a lump sum so you are left only owing a few quid on the loan, then when your next monthly payment clears the loan its classed as the loan ending of its own cause, rather than you clearing it early. Depends on the company however.
I was aware of the early repayment fee, but hadn't thought about an overpayment ......... interesting idea - I'll ask
