As nice as they look... they are fricken expensive.
The OEM Hyundai mudguards for the standard GT, and former GT Sport, were only something like $90 front and back. And they are genuine parts.
The 2018-2020 OEM Mudguards do not fit the N-Line. It says it on the Hyundai Accessory Resource Center (ARC), and on the instructions for the part itself. (The front says they will, but however they will not, as my Dealer has tried to, and failed miserably)
