Most petrol family cars are less than 1500 kg in Europe. Americans are used to overweight cars and that's spreading to here too. Though it's often a problem since most city parking spots are smaller than huge cars like Tesla model Y.
Based on your experience? My parents use their Golf 7 to drive down south to Italy from Germany every other year. Two adults, two teenagers, and one small dog fit in better than into my dad's late 2000s Mercedes S class
Half of Germany drove to Italy with their VW Beetles back then. It’s a traditional thing. However there are some neighborhoods where with second child family buys their Mercedes V class or VW T6. I prefer those over the ones having Ford Fiesta as a family car.
