ELI5: Why don't car companies create aesthetically pleasing car bodies (Lamborghinis, Ferraris) that have an everyday car's power and durability, but the looks of a supercar?

For instance, the guts of a Honda Civic, but the body of a Porsche... or the guts of a Volvo, but the looks of a Jaguar?  I remember kit cars where you'd take a Fiero and put a Lambo kit on it and it would look awesome.  Why not just make a production car along the same lines?

Most major car companies own these boutique brands. Putting that kind of style into a typical car would devalue their own brands. 

Also if your car looks like a lambo but performs like a civic it's honestly less impressive then just owning a civic. Outside of teenagers you wont find a market.
