Swift Dzire LXI(O) is just another Swift Dzire Lxi, but with a few more interior options. It is not offered with ABS and getting the ABS fitted as an aftermarket addition will cost you heavily. We would like to suggest you to go for the Zxi variant, sure it would cost you more, but if safety is your concerned then the top end variant is well worth it.
According to your numbers your daily run is less than 35 KM, If you are planning to buy the diesel variant of the same maker it will cost your around 1 Lakh more that its respective petrol variant. Since your daily run is not that much it means that 1 Lakh which you pay extra for diesel is not going to give good returns. Now if we calculate the avg. price of Petrol is Rs. 72/litre and with a milage of 18 to 20 KM/litre you will ride 25000 to 28000 Km in that Rs. 1 Lakh. It means for nearly 1 and a Half year (16-17 months) you will freely ride your car. One more thing is the resale value of the car. The petrol car life is obviously more than that of diesel + for the maintenance of Diesel engine you will have to loose your wallet. Think twice. Work on your requirements. But my suggestion is undoubtedly a petrol car. If you are riding 35 Km daily it means you spend less than 1 hour in a car out of 24 hours a day. Go and buy a comfortable massage chair out of that remaining 1 Lakh and spend 2 to 3 Hours which you spend on normal office or home chairs. Good luck
