if compareing Maruti Alto Lxi and Hyundai Zen Xing which is better.

Alto is a lower segment car and is a basic commuter. Santro Xing belongs to a higher segment and is much better car. the engine is smooth and peppy, built quality is much better and so are the other mechanicals.it has got the best quality interiors, even in its class and is second only to its cousin i10. Overall, Xing is a much better package and buy it if you want a good, solid, decent car. If you are on a tight budget and mileage is your main concern, go for the Alto

Ofcourse Santro Xing, there is no car called Zen xing!

We do have Zen Estillo but it looks pathetic, yukk!
