I want to buy a dirt cheap hearse and turn it into this:

Some sheetmetal, cheap mad max hack job, and some fake machine guns (which would probably cost more than the entire car) so I can have the hearse from twisted metal. maybe some wicked twin turbo mill up front and no handling upgrades long term. Then go to that wasteland festival.

I have no idea what the hell else I would do with it other than that though.
