It has to be fitted from the factory. I wouldn't trust the dealer with such an install. That apart, I don't think FIAT offers such an option, do they? Also, Punto is no Swift. It'll be perfectly capable in the braking department even without ABS. Good driving practices can ensure ABS never kicks in, ever. Ofcourse, god forbid some exigencies. Just give it some better tires. The OEM JK Tornadoes are really cheapo tires. Go for the Active. It's my favourite in the whole model range. Either the Active or the Mighty 90. Cheers.
