This is a city car, not a road car. I will let that predefine my comments, because they aren't going to be nice. RS - is that supposed to stand for Rally Sport? You've got to be kidding me, in a Yaris!? I love B-segment cars, they are some of the most fun to drive because they have manageable power that you can work with and not get bitten too hard, they are light, tossable in the corners, and typically have a fun-oriented demeanor. The Yaris is just stupid. The center-mount instruments are ridiculous, I don't care if you chose to spend your hard-earned money on a Yaris and feel the need to say 'they're OK once you get used to them' - they aren't, I shouldn't have to get used to something. In a normal car, my eyes are on the road directly in front of me, and a fraction of a glance below that I can count on my instrument cluster telling me what's what. On the Yaris, I have to take a full glance towards the middle of the car, and if I look up I would be looking at the right shoulder of the road...how is that in any way better? It's a cost-cutting measure so they can make the car multi-national (steering on different sides) and not have to re-arrange the steering column. And speaking of steering, that has to be the worst steering wheel I have ever seen in a recent automobile - a $10K Kia has a nicer spinner.
Continuing my disapproval, mileage is not that good unless you're strictly driving sub-80 km/h. Anything over that and it sucks gas like a C-segment car, or more. With the archaic 4-speed auto revving at about 3700 RPM at highway traffic speed, it's fighting just to keep up let alone have the gumption to pass anybody. Around town it's zippy enough, but a highway cruiser it is not.
Along the lines of what another poster said, I also found the ride to be unsettled and the steering unresponsive. There is no confidence of direction, road feel or stability in this car - I would hope for a heavier weighted steering at speed. The seats are uncomfortable on long distances, cargo space isn't that great, material is visibly crappy (it doesn't have to be, Hyundai does it better) and overall it just feels cheaper than it should be. Wrapping this all into a (in my opinion) crappy package and asking over $20K for it is robbery. Save your money! Buy a 2-year-old Ford Fusion, put some money in the bank, and don't be tempted to stab yourself in the leg every time you wake up and see a horrible Yaris in your driveway.
