Well, all I know is that when I arrived at around 1:30 pm I had one convertible, a sebring, to choose from. It had over 25,000 miles, it was filthy looking from the red dirt and it was a base model. They told us that we could call in the morning to see if any other convertibles (sebring or mustanf) were available and we could swap out. Well, we did call the next morning. Not to see if there were any convertibles available but that our check engine light came on.
When we arrived to swap out, we had a choice of 3 sebrings to choose from. We took the one with 25,000 miles but it was the cleanest looking. In addition, it was a luxury model sebring.
As for luxury models at LIH I didn't see any. To be honest, I wasn't paying much attention.
