I bought Santro Xing XL in September 2006. Simultaneously my 2 friends also purchased different cars, one chose Wagon R Lxi with LPG Kit and another one chose Indica Xeta (Petrol). I havent drove Wagon R yet and my experience with XETA was not so good. Its very noisy car.
Santro is very silent car and no other car can compare with it on this, I am sure for it. Also the interior design/material and look is far way ahead then others in its segment. Power Steering is so thrilling and in traffic it certainly me a lot of control to manage my way out.
Still I feel that with AC on it certainly looses its power and I can feel power lowering down as soon as I turn on the AC. Hyundai should work on it. But except this in my opinion Santro Xing XL is matchlessly super in midsized family car segment.
I love my Santro Xing XL.
