I have purchased Chevy on 31-Aug-2013 & within 5 months I have driven 8000 KM which includes long driving Mumbai-Goa-Mumbai, Mumbai-Nashik-Mumbai & Multiple times Mumbai-Kolhapur-Mumbai. As car is of great comfort & plus point is mileage.I have get mileage of 23 Km/L.
Maintain the speed between 80-100 km & you will get awesome mileage. Most of the time, I have traveled with my family 5 people including me & my family members love this car.
I will suggest if you are looking for hatchback in range of 5-6 lakh, you can prefer the Beat which will satisfy your needs & beat you personality.
Best of luck
