But it's not fair to compare a 2012 model prius with 15 model vezel. If you want to put up a statement regarding their prices please compare both cars of the same model i.e 14 with 14 or 15 with 15. And vezel will be the obvious choice then.
Plus the interior plastics of Prius look real cheap to the eye.
Parts will always be a problem no matter what car you buy as long as it's a jdm the problem will exist. So you just can't argue on that. If you're going to talk about parts better just buy a corolla.
But ofcourse the prius has a lesser drag coefficient and hence better highway mileage. So it's definitely a plus to the prius for it's better shape
