I am driving my car in and around Chennai. It's city and highway friendly and I am getting 16 plus mileage which is good for its size. The best part is I don't feel like driving 7 seater because of its length and great front visibility.
The primary reason for choosing Alcazar was because of service back up and VFM. For 21 lakhs you get all gadgets which is really good. Talking about space, I would say 4 adults and 2 kids for long journey. Boot space is fine for a couple of suite case. I never felt under powered but you may need to change gears in a city traffic and I guess, it's same for all SUV.
