Cars Q&A

Hi, Actually, I am planning to buy a car. My budget is b/w Rs. 2,75,000 to Rs 3,25,000. I am a bit confused between Maruti Alto, Wagon-R and Hyundai Santro X-ing. I am thinking from all perspectives A/c, Mileage, Space, Maintenance, Looks, and Resale etc. What is the right time to buy a vehicle, so that maximum discounts can be availed? Also, I am working at IBM Daksh, how much corporate discount is offered to this organization? My friend told me that dealers also offers some deals like free Seat Covers, Steering cover, Stereo etc. I will visit various dealers to get the best price. What sort of benefits can be availed other than cash through dealers?
