i sell car finance for a living, so i've seen some pretty sorry cases! If you are funding a 10k 182 for 13k and paying 340 per month, you want your f**king head looked at. I'm guessing you live at home and have nothing else to spend your money on??
If in 12 months time you get pregnant/in love/mortgaged up and you want to sell the 182, you will still have 13k outstanding (after interest) and the thing will be worth about 7, leaving you six grand up the spout as opposed to 3 which you were with the mini. It does not doesn't take a genius to work out you are being a Turd if you go ahead with this.
