Cars Q&A

I want to buy a hatch in around 5 lakh budget but am confused between hyundai i20 magna and ritz zxi.I will keep it for a long period(More than 5 years) My preferences are comfort,space,practicability,low maintainence,fuel efficiency in that order. Also I want to know that the period most suitable to book the car(one that would offer a cheap deal) and how i get the best deals from dealers, as it is my first car. Kindly tell me about the accessories that dealers can offer along with the car and specially about sill guards(price and use). Thank you.
