With gas prices expected to eclipse $4 per gallon in the near future, many people fear the price of used fuel-efficient cars may experience a significant jump. Though the cost may rise a bit, the National Automobile Dealers Association (NADA) believes it will not be enough to change consumer behavior.

Drivers have been used to high gas prices for quite some time. While many people are worried that fuel is on the way up, even at a relatively low $3.50 per gallon, motorists are still paying much more than a decade ago, and they have come to terms with that. As a result, shoppers may not change their activity that drastically.

"Considering consumers have become accustomed to gasoline prices that averaged more than $3.50 last year, this time around we don't expect to see dramatic shifts in the shopping behavior of consumers for more fuel-efficient vehicles when prices approach the $4 mark," NADA's executive automotive analyst Jonathan Banks said.

Just because drivers have become used to high gas prices doesn't mean that you shouldn't look for ways to save money at the pump wherever possible. Aside from purchasing a used car that gets good mileage, how you drive your vehicle can have a significant impact as well.

Taking care of your tires is one of the most important aspects of maintaining a fuel-efficient car. According to the Federal Trade Commission (FTC), having properly inflated tires can increase gas mileage by as much as 3 percent.
