H'bout each of them picks an expensive supercar (any, brand new or in good shape, let's say 300k $ or more (so no family friendly audi R8 or Gallardo/430, real mad stuff)) & has to drive it thru town for about 100 miles (in order to show all the misery of a super-car in town) to a Strip-Club, & then each presenter has to "impress" as many girls as possible or persuade em to get in those cars for a "ride", using only car language + car stuff talks relative to a car he brought.
They can do it in form of challenge, with scoreboard & stuff.
