some years ago i worked for a car showroom, it was amazing just how much they would lie and stitch up customers, they would sell them utter sheds with a warrenty then when the car packed up a few day's later they would repair it in there own workshops, and claim the money back from the warrenty company giving them double bubble.
they would get people ring up asking if they had a certain car instock, they would always say yes just to get them down to the showroom, then make up an excuse and try to flog them something else..
then they did that finance for bad credit history, try 40-60% apr
i didnt stay long lol
