I've seen that D1 XD on Ebay as well.The 14.9K one is still on Ebay, and this one was on there for around 5K. It is rough to say the least and XD's didn't have jump seats from the factory as far as I remember so those were added later.
I'd buy it for 2500.00 if it wasn't a complete rust bucket, but anything over 3k is not worth it. Nothing really special about an XD vs an SD except for the AA Yellow paint, decals, and roof rack (if it still has it).
