I can't compare it to the Yaris, but it is the worst car I've had in almost 40 years for interior durability.
The 'hard plastics' (ie, not 'soft touch') are very easily scuffed and marked. These areas are the lower door trim and sills, both at risk of being kicked when getting in and out. Centre console and the dash glovebox area, at risk from objects or rings. B pillar trim, dinged by the seat belt buckle.
The factory fitted mats were showing signs of wear at the heel points within the first 1000 miles. Replaced with aftermarket mats to preserve the originals.
Now on 4500 miles at one year old and the drivers seat bolster is starting to show signs of wear. The leather and suede surface.
It is difficult to avoid rubbing that area getting in and out of the car in a tight garage or when the door can't be fully opened.
Yes, it is bad. I'm being as careful as possible with it, to avoid marks. Mostly only myself in the car, no dogs or kids.
Keep telling myself, don't worry, enjoy it for what it is, a brilliant, cheap sports car.
