The "Show and Shine" event was part of a campaign for the Children's Miracle Network, fundraising for Northern Light Eastern Maine Medical Center and Acadia Hospital.
It also gave kids a chance to run around inside some Jeeps.
Organizers said through show registration fees and donations for a bean bag toss tournament at the event, they were hoping to bring in about a thousand dollars.
"It's more important to give back to them because it's our next generation that's coming into play...either help with their medical bills or even just having a blanket while they're there at the hospital," said Kelly O'Neal, the membership coordinator at Bangor Sam's Club.
There was a trophy for what was voted the best Jeep there.
Some visiting all the way from Florida came to enter their truck and give back.
