According to TMZ, Seth is a proud new owner of an exact replica of the DeLorean from "Back to the Future."

Seth's people confirm the "Family Guy" mastermind purchased the DeLorean earlier this month. A source tells us Seth is having about $20,000 worth of customized equipment installed ... making it the coolest thing on wheels since the motorized bar stool.

One source -- who was lucky enough to sneak a peak at MacFarlane's unfinished DeLorean -- said the car already looks "insane."
