I'm assuming the OP doesn't just want push start but keyless operation, which means you don't have to take the key out of your pocket/bag. The car locks, unlocks and starts with certain actions while having the key in the required proximity, usually very close.
It's not a must have feature but is convenient. Especially when you have your hands full and need to access the car.
