(NAPSI)—A recent study by Interactive Advertising Bureau shows that 96 percent of consumers begin their car search online. In fact, millennials spend as much as 12 to 13 hours researching cars online before making the decision to buy.

Buying a used car requires even more research and there are lots of places online to do so. Here are four points to help you avoid wasting time.

1. Know what you want. Have a budget and clear idea of the type of car that’s right for you first. Use online reviews, too. Getting pulled off track will overcomplicate things.
2. Where you shop can be just as important as what you buy. Choose reputable websites and dealerships where vehicle history information is readily available.
3. Get a good handle on what the car you’re looking at is worth. That way, you’ll know when a bargain looks too good to be true.
4. Find the cars you want and avoid the ones you don’t by starting your search using vehicle history at Carfax.com. Choose 1-Owner, no reported accidents and more, plus every car there comes with a free Carfax Report.
