car suited for a family of 2 parents and 2 small children so we need a car with a good space inside and a must to be able to diactivate the airbug in front. also i would like a bagage of at least 450 liters with the more the better. I belive a car should be less odor and fuel efficient but those are secondary. would be nice if the car is under 12 seconds to 100kmh and with max speed over 170 km/h. as i am looking for models in years 2015-2018 there is a good chance you can suggest few options. taken all of that in account i would prefer as small as possible car (width and length) and not too expensive. ideas?
