I have applied for finance on a vehicle the other day including my trade in which has ended me with being £2600 upside down.

The only thing is that i have been max advanced on hp and the max advance only covers my purchase and does not seem to include my neg equity.

Surely the dealer knowing i am upside down would have been better to have applied for a fsla for my new purchase?

What is the best way forward do you think for guaranteed finance?.
