One advice to all the people stop judging the car just because its TATA. It's got a proven engine that was used in Swift untill last year. Yes, I am talking abt the 90ps fiat engine. It's got the same manufacturer for the AMT that Maruti Celerio has. Best in class features. I have read lot of blogs including team bhp and checked with my friends for Zest's after sales service and I haven't seen any negative feedback. Servicing required @15000 km and is not that expensive approx 4-5k. They have got good colors but I would expect them to launch it in black. I would definitely recommend you to go for a Test Drive.
Best Features: Infotainment by Harman, high adjustable seats, good boot space, reverse sensor, climate control
Pros: An automatic car that comes with abs, ebd and airbags which is usually removed by other manufacturers to reduce price. Infotainment by Harman. Touchscreen
Cons: No dead pedal, Reverse camera not available by default. Design lacks a little more style if you compare with Ford Aspire
