I can't help but feel all modern cars are filled with plastic bolted to metal. Which feels rattly and tacky. It's just that some companies use better insulation and tougher materials and better feeling sufaces, which gives the edge over others.
To me this is the last part of a car I would be worried about. I have found quite a few people who like their Hyundai Coupe and value the performance too. There are "better" vehicles out there with equivalent if not better style and features but they tend to be high milage branded ego machines.
Owning a car is for you, not what other people think of you and your car. If you love the styling and can rest easy with the plastic being made in Taiwan and not China, then buy it. Just consider the options and know that whatever car you own, it's only going to be as good as it's owner. They all need regular service, love and sexual attention.
