reliability doesn't count these days, as all cars are reliable generally speaking - even the Fiat - it isn't 1980 anymore
buying a car for it's reliability alone is kinda boring...live a little!
but I agree, the Fiat and Nissan both are about the same in the comfort factor - the Abarth seats, for some reason, felt better than the normal 500 seats.
still, no way I would pay Abarth money for this fashion accessory...if I am going to buy a loud, slow, ugly little city car, and had no other choice, I would get the Nissan, swallow my pride, and pocket the rest of the cash. The Fiat is just not worth it...until you get the Abarth that is
