Overseas Delivery vehicles on dealer lots?
 

I recently purchased a new S60 from a local dealer and the spec page in the window (which usually lists features, price, fuel economy, etc.), there was just a big "OSD". I asked the dealer what that meant and he told me that the car had come via the overseas delivery program and that the GM would supplement the regular inventory in this way. I'd never heard about that before. The car only had 22 miles on it, but I'm curious if that's a common practice or if the sales guy was covering for something. Would love any thoughts... Thanks.
