As several ppl already posted buy something cheap first- especially for high school!!
My first car was a 83' izuzu Trooper; had 189k and a back seat that folded flat . I beat the hell out of it - jumped it, drown it in the river, hit a deer, rubbed it against trees, trashed the interior, hauled friends around, and I even met the girl who is now my wife in it! Man I had some fun in that rig!!
My suggestion is to buy something cheap that suits your needs that has some miles and some light damage, makes the blow a lil softer when u f-#* it up
And save the rest of that cash for down the road.
He ain't that smart, man.
