I recently purchased a Black Insight EX with Navi after careful comparison with the Prius. I concluded that the Insight is a much better value, ($10,000 less than top of the line Prius, although it doesn't offer quite as many options) and is much more enjoyable to drive. I purchased this as a commuter car (60 mile round trip to work) and for running errands. I consistently avg 45mpg (calculated by fuel up to miles driven). Overall I am very pleased with this vehicle and believe it would have see better sales if it was marketed better. Also, contrary to Edmunds review this car is capable of electric only operation although in very limited circumstances (flat level ground under 25 mph).
Excellent fuel economy, very fun to drive (Paddle shifters are great and really assist with passing & merging onto highway). Love the utility provided by hatchback with fold flat rear seats.
Better placement of front seat cupholders, addition of a fold down center armrest in back seat, increase back seat and cargo area space and include some type of cargo cover. EX should have option for smart key entry/keyless ignition, 17" wheels and auto dim rearview mirror and still price under 30K.
