Here are some tips to help you get the best deal on a car:

1. Shop around before buying the car. By doing this, you'll be able to know what different dealerships are offering and what is within your budget. This way, there will be no surprises when the time you go to buy a car.

2. Time your purchase correctly. If you know that a dealership is going to have a promotion or change of staff, then it's best if you wait until these events happen before going ahead and purchasing a car from them.

3. Determine your monthly payment and the total price you're willing to pay for a car. Check what car loan rates are, so you can get an idea of how much money you'll need to save up before purchasing a car. This will help you determine which cars you can afford.

4. Negotiate the price you want to pay for a car while at the dealership. Usually, dealerships will have their own markup that they use to determine how much markup they will add on top of what you owe them if you take up their financing option.

5. Ask the salesperson for a better price if you think it's too high. You can say things like "Is this your best rate?" or "Is there any chance you can give me a better discount?" to see what they can do.
