I drove my wife's Mercedes GLK350 to work last week instead of my Smart ED.
What a let down, the 280HP SUV can't quite come close to matching the Smart from 0-60km/h (the local speed limit). Then again, once the big Merc gets rollin', what a roar! I sometimes miss that, but for the most part, I love driving my strong and silent Smart Electric Drive.
And saving >$100 per month in fuel costs is nice too.
