Car Valley

Sold a mondeo which looked abit dirty on the outside but nothing a wash wouldn’t sort, we asked very specifically if there is anything at all we should know about and that we understood the age related wear and tear but we’re told that the engine is fine there’s no issue to worry about, on route to my mates who is a mechanic and it overheats coming off the motorway, we refill it with coolant (30L in total we put in the car over 3 days) and now when we’ve taken it back they refuse to give us a refund, I’m disabled and autistic and they fully took advantage of my lack of knowledge they are scum bags and should be shut down it’s max that this country allows people to get away with this, I don’t have much money I’m now left unable to go anywhere and without money to get a new car so this place loves to take advantage who have physical and mental disabilities.
