 I rented a Yaris for week in California and it felt cheap, ran noisily and definitely suffered from wind noise.  But I did like the subcompact size of it.  So my fear when test driving a used 2013 Prius C (30k miles) was that it would have these same problems. Wrong!  The Prius C is much more solidly built and does not feel like a tin can. While the interior for the Prius C 2 is indeed plastic (with unfortunately, cloth side door armrests which stain easily), they've done  a great job with a blue/back color combo in my silver C2.  I was surprised that, though lower to the ground, the wind noise was less than my more cavernous 2001 Toyota Highlander that I traded it for.  I could tell that it didn't have the power of my Highlander's 2.5 litre engine, so I haven't taken as many chances with it whipping in and out of daily traffic. But I find it peppy enough, even when entering freeways. The seats are comfortable though a bit firm (I got a special seating pad for longer trips). I love all the onboard electronic screen that allows you to geek out if you wish (I usually keep it on the screen that tells me my average mpg). And to tell you at the end of trip how many pennies your trip cost (often getting 50+ mpg in the city especially in stop/go traffic).The trunk space over my Highlander has taken some getting used to. And I can't fold the  backseats completely down unless the back seat headrests are (easily) removed). Speaking of interior size, I am 5'9" with long legs and I'm comfortable in the drivers seat.  I haven't had rear passengers yet, but just sitting back there I was surprised at the leg/headroom. You really can't tell from the outside of the car. One drawback in the rear seating: The car's electric battery sits below the back passenger's seat right behind the driver.  There's a grill on the rear seat that keeps the battery cool; it cannot be blocked. So that means no legs  or items blocking it. Overall, this is a fun car to drive, MPG is insane, and it's pretty darn cute. Love the built-in bluetooth, auto climate control and an insanely good sound system that rival the Bose system in my Highlander (though it has some challenges with really heavy bass). For my lifestyle, I made just the right choice.UPDATE: I've now owned my Prius C for more than 6 months and continue to love it. I have now driven it for one 5- and one 6-hour one-way trips, respectively, and I was very pleased with the comfort and lack of wind noise. And I've gone as high as 62 miles per gallon. I learned from the dealer when I took it in for it's 5k checkup that oil is changed every 10k. I also had a passenger over 6' sit in the front and back seats. He said both were very comfortable, citing that the back seat gave him more headroom. I'm still not sure if the Eco Mode is a gimmick or not. I do not keep it on for freeway driving because I feel it makes  a  slightly discernable grinding noise. I've sometimes had pairing problems with the bluetooth, but not sure if it's my phone or the car's bluetooth. The interior goodies like auto climate control, bluetooth, and a killer sound system for an economy car is icing on the cake for one helluva car.ONE YEAR UPDATE:  I'm still enjoying my Prius C and pimped my ride a bit with a bra, black/red wheel covers and tinted windows. I have taken a few long road trips like an 18-hour RT ATL-Richmond, VA (and spent $72 on gas RT). Surprisingly comfortable. The Prius C doesn't seem to do well gas mileage-wise when idling in traffic with the A/C on; I get as little as 19 MPG, the equivalent of my 2001 Toyota Highlander that I traded it in for when the car. So, I run the A/C as little as possible when in stop and go traffic. I've also noticed in stop and go traffic the engine sometimes revs and I always fear the car will accelerate on its own. It never does and my Toyota repair person said he had a Prius that did the same thing (he had a long explanation but my eyes glazed over). Also, the car still has no dents in the sides from cars opening the doors too wide in parking lots. An unexpected benefit of having a subcompact car!
