I got the model, and was very impressed. I too found it strange that it arrived a few weeks after the car was delivered. It was completely unexpected, though, so it was a great surprise!
I didn't exactly build my car, either. Another buyer specified it, but then reneged, leaving it open for me to purchase. Thankfully, it was spec'd almost exactly as I would have!
Lambo Calgary gave me a TON of free stuff - I was amazed! Car cover (not a standard option, at least on 2015s in North America, I believe), wall calendar, desk calendar, key chain, winter jacket. Very cool buying experience!
