I have used Eon Era from Nov 2011, Metalic Silver colour with best AC and good fuel efficiency .
Eon has Three stroke 800 cc Engine with mileage 21 km/l.
Eon has large boot space, comfortable seating and Ac with good cooling efficency.
With Tubeless tyres eon give 21km/l mileage even with Ac on condition.
This one of useful car for office goers and even in Metro, s due small in size and good fuel efficiency.
