I've yet to drive one - and I'd bet most people who knock the power and/or 0-60 stats - haven't either.
However, I think 0-60 times and it's stepbrother, the HP rating, are a bit overvalued. Yes, power is good. Yes, speed is good, but there's so much more that makes a car awesome.
Sure, the 0-60 ratings of the Scionbaru are not impressive but that's ok. While the Elise's HP ratings aren't impressive, the sub 5 second 0-60 is (at least I think so).
If everyone wanted big horsepower, there are myriad cars for that.
I think there's so much more that goes into a car besides just 0-60. Steering response/feel/input, handling, cornering, balance, driving position, stance, braking, interior vibe, body/exterior aesthetics. Hell, I had an Infiniti M37 as a loaner and fell in LOVE with it based on that super cool 'silver laquer over wood' interior thing. Insanely cool.
The point is that any number of things can make a car great and even OVERCOME a perceived (or even real) shortcoming - ala a lack of power. Hell, our cars have about 8,816 shortcomings, but the PRO column so overwhelms the CON column that it makes our little cars one of the most highly regarded ever.
I like analogies. I see these cars as Gwen Stefani or soccer hottie Alex Morgan. Both are completely flat chested - nada, nothing. Mosquito bites. However their awesomeness in all other categories makes that reality completely irrelevant. Watch the Alex Morgan body paint video from the SI Swimsuit issue. Completely flat chested, however, she's smokin' hot! All the other stuff is so awesome, it makes the lack of boobages a non-factor.
