Reading the reports, there are issues with it (some minor and a few like the battery burn quite serious). Personally I like the styling and think that it is a step in the right direction; however, I'd be happier to look at them once the generation two comes out and they've worked out the teething issues.
As for the quoted MPG figures, they are optimistic at best. Real world conditions, mixed driving and not mashing the accelerator are delivering circa 40mpg - not bad but not even close to the 100+mpg quoted.
Also, whilst the door opening is attractive, it isn't functional unless you have very wide parking spaces... and where do you find those these days! Lamborghini seems to have nailed this with their scissor doors but the 'swan' style always smell of fashion over function to me.
