I would get a Prius C if I weren't concerned about the lack of safety from being so small.
What is wrong with the Prius C? Never heard anything about them being unsafe... but then, I ride a motorcycle so what do I know about safety?
Simply being so much smaller than the average car makes them unsafe in comparison.
Safety
Standard safety features on all 2013 Toyota Prius C models include stability control, traction control, antilock brakes (front discs, rear drums), hill start assist, front seat side airbags, side curtain airbags, a driver knee airbag and unique front seat cushion airbags that help prevent occupants from sliding under the seatbelts in the event of a collision. In Edmunds brake testing, a Prius C came to a stop from 60 mph in a better-than-average 118 feet.
The Insurance Institute for Highway Safety awarded the Prius C the highest possible rating of "Good" in the frontal-offset, side-impact and roof strength tests.
Either one assuming same price or which one will cost you less in the end that will serve its purpose.
I would lean toward the Prius C.
Toyota has not given the Corolla a good update for a long time and has been passed by even Chevy and Ford in that area IMO.
The 2014 corolla is brand new. It even has standard led headlights.
I'd probably get the c personally. Think it looks nicer and hatchback is useful
The 2014 is "new" yet is still uses the same old motor.
It at best catch's ups to current cars in its class.
Just came back from Costco and I parked next to a c. I would pick the corolla. the gas issue in this case is negligible. Corolla gets 40mpg on the freeway.
You get better fuel economy because you get a better, more powerful engine as it's the first Valvematic engine in North America. If I was shopping for a '14 Corolla, I'd definitely get the Eco model as the Price premium is small and you do get more amenities compared with the Vanilla models. Not even the Corolla S has the Valvematic engine, just the Eco models.The only Corolla that get 40mpg is the Eco version and that cost extra for not much more.
The Prius C is just a hybridized Yaris. The Corolla has more back seat space though since she's coming from a Matrix, she may prefer a hatchback. The Corolla S has a more powerful engine, heated seats, and slightly better sound system. The Prius C has significantly better gas mileage.
Power difference is about 30hp. If she does a lot of highway driving, might be better to go with the Corolla, even though fuel economy is worse. If it's mostly in town, I'd go with the Prius C.
The only thing I don't like about the Corolla is the 1zz engine. That engine has valve train issues...
