Yep, there is some choice involved; but it's not like go to the compact aisle and take your choice from the 5 Versas.
The last guy I saw was heading for the Corolla I was in before he realized it was taken. At that point, what was left was either a HHR(I like them, but so many people don't) or an Impala. He took an Impala. There is a pretty big difference between wanting a Corolla and leaving in an Impala.
