When our 2005 QP was relatively new, this other car pulled up next to us, and these two teenage boys were freaking out and taking pictures of our car with their cell phones. Another time, we came back to our parked QP to see two men (probably in their twenties or thirties) peering through the windows and admiring the interior. Lastly, I was driving with my dad and a friend - over to his house - and, after we had stepped out and were walking to the house, I noticed that my friend stayed behind, staring at the car. xD Yeah, I don't think there have been any female admirers of the car.
Today, people walk by it and don't even notice it. On occasion, someone who is likely more knowledgeable will notice the car and eye it a bit, but that's all. I guess it helps if it's washed (which, since it's an older car with 11 year-old paint, it's not as striking or washed as frequently), but it's otherwise not too amazing to people because the car blends in well. Also, these were made up until 2013 or so, so there are plenty of uninteresting ones out there/plenty of QPs in general. An even older generation would garner more attention, as they are not as subtle in their designs.
