Something a bit different, perhaps?
How could what was once the oldest American automobile marque survive to the present day? Ideally as a successful, profitable brand... it wasn't that long ago that it was killed, so there seems like there should be some potential.
I don't care when the POD is, though- if you even want to go back to 1908 and have a surviving Olds Motor Works independent of GM, or if you think you can save it in 2000, be my guest either way...
