I have been using this car since February 2010 and did upto 10k kms. I personally feel its always better than looking at any two wheel expensive bike.
Coming to comfort, its head room and leg space is awesome and cannot find the same in any mid-size car in its versions. Spare parts are so cheaper than it service costs. Body should have been little strong as I feel most of it is not made with pure iron. Did long drives upto 150 kms and can compete easy on highways with any other small car in terms of speed, control and maneuver.
