Well where exactly is the difference? Architecture operates within the contraints and requirements of functionality, while also having an aesthetic element designed to create an emotional response. The exact same applies to car design.
A Jaguar F-type or Lamborghini Miura isn't designed solely to get you from A to B, they're designed to affect you on a deeper level - you want one because it looks nice, just as you'd rather have a good-looking house than a grey identikit box.
And it goes deeper than just the visual design, too. The interior layout, the noise and torque curve of the engine, the weight of the steering, the chassis balance - these aren't functional concerns, they're subjective elements designed to provoke a response in the driver.
