While many people select used cars with high gas mileage as a way to save money, others also do it to help the environment. But according to Cars.com, there are other ways to go green on the road than purchasing a hybrid vehicle, and the website recently offered a few tips on how to do so this spring.

One of the most important things to keep in mind when shopping for a fuel-efficient and environmentally-friendly car is that a hybrid vehicle is not necessarily the best choice. That's because hybrid versions only mean they're fuel-efficient compared to that particular brand, and there could be a better conventional vehicle of a different brand.

In a similar vein, conventional cars have become especially fuel-efficient over the last several years due to rising demand. As a result, some traditional used cars may be the best bet to not only go green, but save some money.

"Not only is driving green good for the environment," said Joe Wiesenfelder, executive editor of Cars.com, "It can help you save a little green in the process. If you expand your definition of a 'green' car beyond just hybrid and electric vehicles, you can easily recognize some of the benefits of being more 'green' behind the wheel."

The website also highlights the importance of considering alternative fuels. Diesel and natural gas both have their merits, and many automakers have said they are trying to expand the cars they offer that run on such fuel.

Regardless of what route you choose to go green, New Jersey State Auto Auction will have you covered. With a wide variety of eco-friendly and fuel-efficient models at affordable prices, you'll be driving away in the perfect car.
