I see that they are on average about 15,800 dollars. I can make a down payment of $4,000 for sure and possibly could give a down payment of $7,000 if I sell my car that I currently have. However, it all depends if it gets sold or not. I want to trade it in so that the dealership takes off a couple grand off the new Mazda I am trying to purchase. I have a 2002 VW Jetta with a 1.8 T and 107 miles on it and I am not sure if all dealerships offer trade ins and stuff. Please help! Thanks!!
