TL:DR - Neither.

Storytime: When my eldest son (now 24) was about 9, one day he and I decided to go on a grand tour of the high end dealerships in town. We just wanted to go look at the pretty cars.

First, we hit the Lamborghini dealership. We walked around outside, looked at the pretty used cars people had traded in to get their Lamborghinis, then went into the showroom. The sole employee there at the time made it very clear that he was annoyed at our presence, snapped at my son for getting too close to the Gallardo on the showroom floor (the boy was very disciplined, he never touched ANY of the cars that day), and outright asked us to leave. So we left the guy with his otherwise-empty dealership. Don't threaten me with a good time.

Second, we went to the Ferrari / Lotus / Bentley / Aston Martin dealership. They didn't have as many used cars outside, so after a quick lap of that lot, we went inside. There were lots of cool things in there that we, again very respectfully, looked at. They had a Bentley Brooklands in white that really caught my eye. The salesman there came over and spoke with us, asked my son what he thought of the cars, asked if we had visited the gift shop, etc. We visited the gift shop / parts area, saw some neat stuff for Christmas presents. Then we were off to the other dealerships in the area.

The Mercedes store didn't really have anything special, so we just went on to our final stop - the Porsche / Jaguar store. When we got there, sales guys were falling over themselves to make sure we were ok. Since they were so attentive, I kept telling them that we were only there to look at the pretty cars, so they wouldn't miss out on a sale. Eventually the Porsche sales manager came over, offered us some water, and struck up a conversation. We talked at length about our family's history with Porsche, my 928, the current model lineup, the 993 Turbo that was behind ropes at the time, and clearly the star of the showroom, &c. After a bit, while we were looking at a white 911 GT2 that they had in the middle of the room with big DO NOT TOUCH signs on it, the manager asked the boy if he'd like to sit in it. They both looked to me to see if it was OK, and I asked if the manager was sure. He said it was fine, I checked my son's pockets to make sure he didn't have anything pokey, and then the manager lifted the boy into the driver's seat. He let him stay in there as long as he wanted. Then on our way out to our car, he asked if we wanted to see something cool. He then proceeded to open up the entrance to the shop, and walked us over to a silver Carrera GT that was in for service. Obviously we couldn't sit in it because it was a customer car, but it was neat being able to get that close to such a unicorn. We parted with a bunch of smiles all around.

When we got back in the car, my son turned to me and said, "They were nicer than the other places," and I said "Son, that is why we are Porsche people, and not Lamborghini people."
