The Yaris gets great gas mileage and is easy to drive. For a small compact it's actually roomie inside. Controls are easily accessible and the overall feel of the car is that it is a well made product. I've had no mechanical issues to this point.
This is my second Toyota Yaris. My last was a 2009 and I opted to replace it with a 2011. I am so impressed by the changes and even more impressed that they left the things that I love about a Yaris. Biggest improvement is the change in the back seat head rest. Love the cup holder, sounds petty but they are amazing and sadly missing in the 2012. Handling and performance is great and the mph is great. Wonderful city car and feels like a much bigger vehicle in the inside. The car sits high and is easy to get in. I prefer the look of the outside vs the angles of the newer version.
I have owned a couple other cars in the past 7 years. One of them was a 2000 VW Beetle. I loved that car- who doesn't love a small car with a roomy interior? However, it was unexpectantly absurd to maintain - the nonsensical Tetris construction of the engine required me to go to the dealer for absolutely everything that needed changing- even the headlights. I couldn't even easily access the battery! It also got poor MPG - another unexpected surprise. When the Beetle got very old in years, I turned it in. I wanted to find a small car with a style similar to the Beetle with comparable roominess, but a better engine and better MPG. Meet the Yaris. An adorable 2-dr model hatchback with an unreal amount of room for both the front passengers and the back passengers (something the Beetle could never offer). For a better idea of just how roomy it is, I am 6' tall and my friends are all between 5' 11" and 6' 3". Yeah. The interior also fully utilizes spaces I would never think to use - there are bottle holders in the door, cup holders that come out of the dash, and even a handy misc. compartment to the left of the driver's seat. The seats are incredibly comfy and conform more to my spine then the Beetle's 90 degree seats. To top it all off, it gets 35 miles to the gallon. It gets further than my last two cars - on a smaller tank! To top off the last top off, it was much more affordable than the already affordable VW Beetle and has one of the most efficient engine layouts I've ever seen. The Yaris just exceeds every expectation I had for the model. I would recommend this to those equally frustrated with their past 2-dr hatchbacks because I have yet to find a single thing I don't like about my Yari-chan.
