I have heard that there is a way of claiming car finance back from companies due to the finance originally being mis-sold or errors in the agreement. Companies like cartel are advertising that they can get money back but I know that they charge a lot of money up front and I haven't got it.

Has anyone done this on their own, and if so would they be willing to set me off on the right path. I have requested a copy of the agreements from 3 companies and only had one back so far. Don't know where to go from here as the legal jargon is confusing.
