I got to sit in one at my dealer a few weeks ago. It looks really great in person and is quite comfortable. I sat in both drivers seat and rear seat. Rear seat is quite roomy. The Lincoln spokesman spent quite a while showing how the dash functions. The engine was running all that time and most of the time, it was hard to tell it was running. It had the 2.0. He said they aren't allowing test drives at that time because of very few fully complete vehicles and wern't taking any chances.
I put a deposit on an Aviator that was in transit, but after several weeks and zero movement, I went with a 23 Nautilus Black Label that had just arrived. So far, I'm very pleased with it. Getting the 2.7 V6 was worth staying with the 23 IMO.
