In my far younger days I had the great good fortune to own a Morris Mini - the original doghouse, not the modern pastiche. That car did weigh 600 kg, and I happen to know for a fact that six men could easily pick it up and carry it a distance. I also know that it had a length of very close to 3 meters, and that the basement ramp where those six men put it was 3.10 meters wide. As they said when they fetched me, "You may wish to grab something to drink".
