Are you getting the lowest price possible when you buy a new car? There are ways to save even more than you think.

Everyone knows not to pay the sticker price. But how low can you go?

The staff of Consumer Reports found that unless a car is very popular, car buyers today typically get at least 10% off MSRP. The biggest percentage discount was on the Toyota Camry at 15%, followed by the Honda Pilot at 14% and the Volkswagen Jetta, Subaru Outback and Nissan Altima, each at 13%.

"You can walk away from a dealership. If a dealer doesn't give you the answer you want, you have the power of your two feet," says consumer advocate Michael Sacks.

If you don't like to haggle, there are car-buying services that offer guaranteed pricing. Consume Reports has one, as does AAA. You can also find them at warehouse stores like Costco and Sam's Club, and through insurance companies like USAA, Geico and Farmer's.

You can find out the dealer invoice price at websites like Edmunds or NADA -- although experts say that with incentives, the actual dealer cost may be lower.
