That's an apples and oranges comparison sir.
Racks are purely functional. Cars are not. If they were, any car would do. That's why we all have different tastes in cars.
On a different note, about 8 years ago I went on a road trip with some college buddies up the east coast. The more and more north we got the less Mustangs we saw. Once we got past Tennessee it was like they were an endangered species. So I guess its popularity is regional.
Oh and I don't count older Mustangs in my dislike. They are so rare and distinctive looking.
And lastly, I will hate on any car with a giant wing for a spoiler and an exhaust system that makes the car sound like a small plane, motorcycle, angry bee, or fart cannon.
