My delivery was with Maserati of Washington.
My sales person kept me up to date with the progress of the car as it made its way to the dealer. Once it was there, he gave me a call and let me know that it was there. They cleaned it up and my salesperson took photos of it and sent it to me. I arranged a time to go pick it up, and he also offered to deliver it to me. I happen to be moving at the time as well so I needed the extra couple of days to make sure the garage has at least one open stall.
The car thus sat in their enclosed garage/work-shop for a few days, parked among a gathering of Ferraris and Lamborghinis.
When I arrived, the salesperson lead us to the loft area in the Lamborghini portion of the dealership, so my kids could watch cartoons while they wait. My wife goes over to the Ferrari portion to get some coffee, and I go off to look at my car. The salesperson took his time answering any questions I had. I took a few pictures of the car at its cleanest state, with a backdrop of aforementioned Ferraris and Lambos. We then walk back to the loft, and the finance person came by with the paperwork. We signed everything while over looking a showroom full of Lamborghinis, where a used Aventador LP700 has a "sold" sign on it. I asked how much it was sold for, "over $500k" was the answer.
The kids pile into the back seat of my car, dirty shoes and all.
Overall, I wouldn't say the experience was surreal or anything. It's definitely several notches above buying a new BMW or MB for example. Everything was pleasant, unhurried, and comfortable.
My service experience had a surreal moment, but that's another story.
