As the school year rapidly approaches, many families will be faced with having to bring kids from activity to activity. This can be especially tough if parents are involved in carpools and will need a bigger car to accommodate all the children. Luckily, used SUVs have dropped in price since January, and there are certain models that stand out above the rest.

According to a study conducted by CarGurus, the most cost-effective used SUV for families is the 2008 GMC Acadia. This spacious vehicle can seat eight passengers, making it a good fit for parents who have to take lots of kids from place to place. Additionally, it gets an efficient 24 miles per gallon on the highway, all for under $25,000.

As for crossover models, the 2008 Honda Pilot is an excellent pick, experts say. It can fit eight children as well, while costing drivers under $20,000.

"If you are looking to upsize your car and save money, now is a good time to be shopping for used cars and specifically for SUVs, crossovers, and minivans, which have not seen the dramatic price increases of many compact models," CarGurus CEO Langley Steinert said.
