I recommend the high-tech solution of a hanging tennis ball.

I think you can get the kit, complete with ball, thumb tack, and string,
at Best Buy for $9.95.

I always hear this suggestion, but who wants tennis balls hanging down in
the middle of their garage?

I only use the garage for a car in the winter- and I don't spend a lot
of time out there when it is cold. But if I'm working there in the
winter- or for the summer- I have a hook on the rafter a few feet away
that hold the tennis ball above my head.

We do it more for the crap on the sides of the garage than the depth-
but it is nice to have the car in the exact same spot always.
