I'm not sure that matters to your average buyer. BMW, Mercedes and Audi have all done well regardless. Its a visual touch unique to the top trim... its been going on forever in this businessNot sure if the quad exhaust pipes will be the standard for the regular models too because most of the information out there is for the Giulia QV. I think it should come with the regular models too because just having dual exhaust pipes will make it look like it's lacking something in the rear.
