Be aware of their sales people. They won't give sufficient information to crack the deal.
e.g. when you are negotiating the price negotiate on the following things.
1. Discount on Ex Showroom
2. Free accessories - Tefflon, Mud guard, Matting, Stereo system. Negotiate for 4 speaker USB one.
3. Auto Insurance: Generally you will get discounts from outside. So don't buy from them. They have approximately 3000 Rs margin.
And make sure, you crack the best deal. These guys are expert in bluffing. So cover all the parts.
