We purchased our second 5er at the show in Illinois. The unit was being shown by the dealer who sold us our first unit. We did not buy our first unit at the show. Looking at your questions - both transactions were the same. I felt we had good bargaining at the show because there seemed to be some sales quotas to achieve.
Yes there were things that needed fixing when we took delivery, but we also successfully negotiated for additional work/improvements with which we were very pleased, 
My experiences were very positive and it didn't matter where it happened, but it did matter with who we were dealing.
Good luck in your search.
I should clarify. We did not actually buy the actual unit shown at the show, we ordered and got a fresh unit. That said - the 5er we received had a different sofa and chairs which we did not like. We pointed this out using pictures we had taken at the show, the dealer then swapped out the sofa and chairs from the unit that was at the show.
Had we bought the actual show model we would have looked for a deep discount and would seal the deal at the last day of the show, in the afternoon, after a close inspection. Yes there are disadvantages to buying a show model but I would be using the savings to step up to something better - so what would be the trade-offs then?
