Not that it contributes anything to the conversation, but the 2015 NA Scion iA / Yaris iA / Yaris sedan in NA is definitely a Mazda 2 and not a previous gen 3. And it is built by Mazda for Toyota in Mexico - they roll off the same assembly line.
Dude, im driving an '18 currently, its bigger than a 2 (was next to one today), looks nothing like the 2 and EVERYTHING is Mazda inside down to the floor mats with iA in them...
The Yaris is based on the Mazda 2. Has been since it was a Scion iA.Saw an actual 2 last night and its MUCH smaller than this Yaris rental.
