Are Audis a renaissance of the body in different sizes like Devins or Buchanans?

Yes, this is the brand new Audi A7. You wouldn't have noticed? It looks like all the other Audis, specifically the A5 Sportsback or the A4? No, it's really a different car, even if you don't notice. For example, it's longer than the other mentioned. But having been mistaken myself, I honestly must say, they really look alike a lot.
It's almost as if the successful practice of Bill Devin producing many different (fiberglass) bodies with the same shape fitting different chassis and sizes is coming back. You want an Audi? Do you want 4.2, 4.5, 4.7 or 4.9 meter length? Well, then take this one or that one, they all look the same basically. It's like buying jeans, you have picked the brand, now it's about size. I think this is the wrong strategy with cars, especially with such expensive cars. And it's a bit boring and lacks imagination and innovation as well. BMW does a bit the same, but at least the different cars have more unique design features, same with Mercedes. I prefer cars that look unique and special, that's probably the reason why I like older cars so much ....
