From what I've read here, you still have the Merc in your possession? Surely that has to go back ASAP, it's only ever going to decrease in value as time goes on, reducing the amount you can reduce the debt by?
I think the problem would be in settling the difference between handing it back and the value of the vehicle against the amount owed, given that there aren't the funds available to settle that.
I could be wrong, but that's the way I read it.
That is the crux of that part of the problem... clearly, if it were sold for say £14,000 then it would
only require £3,300 to clear the agreement. This would be required within seven days... on the other hand, returning it would require me to pay £8,400 to settle my half of the agreement (the finance company taking the car as their £12,000 half), possibly over an extended period of time, and based on what I can afford.
The apparent discrepancy here is that if the agreement is settled by me selling the car, I am rebated the interest from the remainder of the agreement, where as if the car is returned, then I am liable for half of the full agreement.
However, with the car now three, soon to be four payments behind, I have basically run out of time to sell it so it either gets returned or it gets repossessed.
I do not have the car currently, but do know where it is, and am trying to get it returned/arranged to get it collected.
The Insignia is currently leased out, but should be settled fully by the end of July...
