I'm amazed by how many ads I see for cars in the paper and on TV that only mention a monthly payment amount instead of the price of the car. Just because I can afford the monthly payment does it really mean I can afford the thing I'm buying?
Ask yourself: How much will this product cost me if I finance it? How much will it cost me if I don't finance it? Sometimes neither price will seem that good if you think in terms of parting with all that money in one, fell swoop!
I've been going with this idea lately of never financing anything else in my life. What's this mean? It means I definitely need to save my money if I ever want to buy a car, or even a house. Now, the idea of buying even a moderately nice used car for $10-$15K seems like a huge amount of money to me. If I hate the idea of even parting with that much money for that car, how could I even consider the idea of a nice, sporty new car like a BMW or Lexus, or even a Porsche?! Yeah, a nice new car is a lot easier to get when you write a check for only $300 or $400, but think about how much you're paying for it. Not only are you paying interest, but you're losing the interest you could have gained if that extra money you paid was instead saved.
