A quote: "Subject To Financing..."
This clause appears on buyers orders that we sign for a car. It means the deal is not done yet, even you think you are signing a contract. Then 2 weeks later the dealer calls you up and says "your car loan fell through." Why is that? They ran your credit report, right? They knew what you would qualify for. This is a common loan scam. You should not buy a car first then worry about financing. You don't do it with a house, so why do it with a car? When you buy a house, you MUST have your home loan in order first, so have your car loan in order before you shop for cars.
I just bought a new car and couldn't be happier - at the second dealership I tried. The first one was so slimy I'm still washing myself off.
