First, I live in NYC, and I often drive into Manhattan where the roads take daily punishments from many hundreds of thousands of cars--the roads are atrocious, what's worse is traffic. The Prius C's abilities to maximize gas mileage in city traffic situations is its most compelling feature. Frankly, I reckon I can get more than 53mpg. However, the C is only slightly easier to park than the regular Prius. I can probably fit into a few extra spots that the regular Prius cannot. The C is basically a "regular" car, with respect to parking. The Scion iQ also appeals to me: it's 4,000 dollars cheaper and about 30 inches shorter. I often drive alone. THis car should make parking a bit easier! So, Prius C = maximum efficiency, I don't have to feel bad as traffic inches along (during rushhour) Scion iQ = solves the parking problem, not as fuel efficient. So, that's me, what about you? Do you consider the Scion iQ a competitor to the Prius C?
