Maybe that's why there are complains about yaris 1.3 not climbing easily or not climbing at all at Monal.
Even the left arm elbow rest is way behind.
city's rear seats have more space than yaris especially the leg room.
Tell you what you can visit any showroom. first sit in the front seat of city and set that seat as per your requirements and then sit in the rear seat. Do the same for yaris also. you will easily come to know the difference
