if you have the resorces, find a concept car and you can use that as a prop. If not you can always try for a space suit with the back ground on mars or somthing..
even better.. make the back ground seem like your living on the moon in a bubblesphere with your model mowing the lawn and tending to a house like its back in the 1990...
it would be pretty cute...
now that is something i would want to do
