If you are in the market for a used car, it's most likely because you are looking to save money. Used cars are significantly lower in price compared to a new car, but this doesn't always mean that you are saving the most money possible just because you are not buying new. Here are four more ways you can save even more:

1. Get a Good Interest Rate: If you are financing the used car, it's extremely important that you find a loan with the best possible interest rate. The first step to doing this is fixing up your credit report slightly. You should fix mistakes and pay off any small debts. On top of this, you should not take out any new credit, which can only hurt your ability to get approved for a car loan, let alone a car loan with the best interest rate. 
2. Don't Go Upside Down: You should never buy a used car if you are going to go upside down. This means that you are paying more than what the car is worth. This is why a good interest rate is important. It's also important that you know the value of the car that you are buying and calculate how much you are spending once the loan is done being paid off. If it's significantly more, it's much better to find a car that is not going to cost as much or negotiate on the car price. 
3. Negotiate: Speaking of negotiating, it's extremely important that you negotiate on the car price as much as you can. This is going to save you even more money. Besides, many used cars are priced more than what the seller is willing to sell the car for simply because they are expecting the buyers to negotiate, so don't be afraid to do this. The seller is prepared for it. 
4. Know the Condition Value: Finally, you should know what the condition value of the car is. If you go onto Kelly Blue Book, you can determine what the car should be worth based on it's condition. Sometimes, the seller will advertise for a price that is more than what it is worth simply because they didn't have the condition value in mind. This way, you know you are not paying more than what you should be. 

When you know these four ways to save even more, you are going to get the most out of your used car inventory purchase.
