When I was still in high school, so maybe 16 or 17 years old, my father had a little Suzuki hatch that was probably similar weight to a Mini. One day he accused me and my friends of moving the back end of it. I was really pissed off because (1) I didn't do it and my nerd friends certainly didn't do it; and (2) he assumed that I needed help to lift his stupid car. So I started wheeling his stupid car around, by myself, just about every day purely to piss him off. It was a lot easier to lift than a Mini because I could grip the bumper bar, press my back against the hatch, and do the whole lift with my legs from about a half-squat position. Whereas with the Mini I had to mainly use my back/arms/shoulders to lift it.
