The test drive. Many of us have the same thought during the car buying process, standing in the dealership, debating various makes and models, finding something we like, and then having the salesperson throw us the keys: What in the world am I lactually ooking for?

Cruising around in a new car sounds like a lot of fun. But the truth is you may have just a few minutes to see how you like driving a given car before you’re asked to plunk down your hard-earned cash and buy it. There’s a ton to think about on a test drive. So it’s important you’re prepared. Luckily, the car driving experts at Consumer Reports shared how to prepare–by planning your route and knowing the cars you want to test ahead of time.

First and foremost: You want to test drive multiple cars in one day. Comparing any new car with your old clunker may have you head-over-heels in love with whatever you test. So if you haven’t decided between a sedan and crossover, great. Test drive both. If you are considering a performance trim and base trim of the same vehicle, test drive them both. Call a few dealerships and find one that has everything you’re considering in stock. The benefit of having a list of a few cars to test drive is that it’ll be harder for the salesperson to hustle you into some luxury car that you already know you can’t afford for your second drive.

Next, you’ll want to research the stats of each car. Know the differences and decide which factors are important. If they are driver aids such as blindspot detection and lane-keep assist, you’ll want to take the cars on the highway. If its suspension and handling, you’ll want your test drive route to include some corners and potholes or speed bumps. Plan your route ahead of time.

What are you looking for in a new car? That depends on your preferences. But one great place to start is by listing the things you love and the things you’d change about your current car.

Here’s another pointer. On your way to the dealership it’s a great idea to do a lap around your test drive route. This way you know the route and during your test drive you can focus on the car–not the directions.

It’s wise to bring a co-pilot. Ideally, this can be a family member who will be riding along often once you buy a car. This is a chance to get their input as to whether it’s comfortable and spacious. But in addition, they can handle the salesperson so you can focus.

The final step in the process is to drive away. That’s right, take some time and space before making a decision. Why? Because you’ll be biased toward the most recent car you drove, and susceptible to the salesperson’s pitch. Find a nearby coffee shop or lunch spot. Chat with your co-pilot or write a list of pros and cons. Only return to the dealership when you’re sure about your decision.
