i've been waiting for that ever since Hodgins shot him that "oh no you di'n't!" when Booth made that "toy car" quip. i'm like "wuh oh. there's gonna be a throwdown. Grease-style." cos i'm thinking Booth is a little Dirk Pitt with his classic cars...i mean, granted, you ain't gonna get rich being an FBI agent, but i would imagine he's creative with his investments...even if he can't have an entire hangar full of 'em...
