Save/Spend/Give--awesome! How very Dave Ramsay-esque!
I had a couple thoughts. He could "give his $1 per week to his "giving" envelope and before Christmas, take the $$ and buy Toys for Tots. (In his case, he could buy cars!)
If he likes animals, you could investigate Heifer International which provides goats, pigs, chickens, etc to third world country families, who then breed and pay it forward. It truly is life changing for those families to have an item of livestock.
Have fun!
