The 2017+ Elantra sport is starting to get a decent aftermarket going, the GTS... not so much. unfortunately the sedan seems to be the golden haired boy of the Elantra family and the GTS will be playing second fiddle me thinks. I'd like to see more manufacturers getting on board. I think its just a matter of time. I drove an '07 Tiburon GT previous to this and everyone and their brother made parts for it.
