Can't you borrow that Starksy & Hutch car that's down the road from you?
And for god sakes, go as Hutch!
(I know it's not strictly an eighties film, but what the hell!!!!!)
Or, other suggestions.
Beetlejuice. Not easy to replicate, i know.
Scarface. Blood soaked suit, nice big gun.
I reckon Indy Jones is a sure winner tho.
