I own a 2018 SL.
Yes, the interior is almost all hard plastic and cheap. Odd interior design too. No hand grab handle above the drivers door even though the headliner has a recess for it.No coat hanger hooks on any of the hand grips over the doors. Really oddly shaped center arm rest in the front seats. Itís tiny and shaped like a bicycle seat cut in half lengthwise. No center arm rest in rear seats. No CD player even with the upgraded Bose stereo. No remote rear hatch release.
And the cheap hits donít stop. Disappointing for a $38,000 car. Our 2014 Prius V came with a far nicer and useful interior. Of course, it doesnít have 2018 Pro-Assist features.
Still, the car is fun to drive.
