First post on here. Don't have a Karma (can't afford one but looking at the Ampera) but I was wondering what it was that made you purchase your car in the first place. If you could vote on the poll it would be very interesting.
I think you'll have a hard time gathering meaningful information with a Poll. For starters, there are several other considerations in addition to the ones you have listed, and for many owners, including myself, it's a combination of factors, not just one.
I agree that there are others - but those tend to be 'heart' purchases which are never meaningful anyway! I certainly know that a lot of people would buy this car on looks alone but, since I'm an engineer deep down, I was looking for the 'head' side of things.
I believe that original post shows that most people have put looks down as the number 1 choice but I like technical things
Also, this poll allows you to select as many of the choices that you want.
