Back in June, there was a video of a guy who bought his dad a '57 Chevy for his 57th birthday. And obviously his dad was THRILLED. But dads ain't the ONLY ones who've always dreamed of owning their dream car.

A guy named Corey Wadden has been on a mission to make enough money to set his Momma up for retirement by the time he turns 25. He's actually making a documentary about it, and little by little, he's gettin' there.

He recently managed to save enough to buy her the CAR she always wanted . . . a 1973 Saab 99 EMS. And he just posted a video of her freaking out when he gave it to her.
