ABS and airbags are mandatory. It's better to get a mid-level variant with ABS/airbag than to opt for a top-level variant without one. The novelty of a new cars fancy features wears off quickly, but the safety features would always remain with you.
I am sure you are spending a good chunk of money on mediclaim and life insurance every year which would eventually help you AFTER any calamity. Think of this as insurance money you are putting in which helps you BEFORE the calamity. The additional money you would be putting in is worth every penny when you have to stomp on your brakes while going at 90-100 kph on the highway and a cow decides its the perfect time to cross the road. The fancy features like climate control, kick ass music system, body colored handles and ORVM and other frills do not help at all in this situation, does it?
Apart from safety features, the second level of features you may want to look for is what would make your daily drive a stress-less affair. For me, it would be automatic ORVM, day-night rear view mirror, foot rest and hill hold.
