I was using this car from last 7 years. It’s a wonderful vehicle loaded with all latest technology. Small but sweet car. This is perfect as city car. Average is little disturbing in city but for long drive it’s perfect. The inner space is quite ok for 4 people even for long drive also.
As I am not from engineering background I am not in position to explain the technology but as a third person I found the car is wonderful. I found this car is really worth to buy at least for city ride.
