This video has been around for a while but Rob Gruhl does such an excellent job at explaining how to purchase a car that it is well worth your time even if you aren't in the market just yet. Even though the focus of the talk is on how to buy a new car, you can easily adapt most of this advice to the used car hunt as well. I've lamented my last car purchase on WalletPop before and I wish I had watched this video before we set foot in the dealership last year.

My favorite piece of information from this video is to remember that you as the buyer have the power when you go into the dealership. There were numerous times during out purchasing that we thought things were iffy but we didn't walk because we got too attached to the car and forgot that we held the power in the transaction. Something that I don't think most people realize when they go in to purchase a car is that, unless you are buying a first edition Dodge Charger, there are thousands if not hundreds of thousands of almost identical cars out there for you to purchase.

I wish we had remembered that when we went shopping, instead I got in the mindset that this is the only one we will ever find in our price range and began justifying this and that to ourselves, eventually purchasing the car and getting suckered into GAP insurance and dealer financing. Both of which we ended up switching within a month and saving a bundle. Remember, "If you're doing it right, you'll feel like an ass."
