My first 6 cars were Mini's
I would buy MOT failures, patch them up (they always had floor pans rusted through); get them through my friendly local MOT station then sell them at a profit.
One never made it, sitting on the driveway for spares, and slowly rusting away until parental pressure forced its removal.
The gear sticks in early Mini's were long sticks poking out from the floor. As the car got older and worn, the gear stick would shake and drop out of 3rd gear on corners - for years I still had the habit of tucking my clutch foot under the gear lever on 3rd gear bends.
Any car "activities" with girls had to be in the back seat as the car was too small. I quickly learned to park facing downhill with the seats tipped forward after I was nearly circumcised when the rocking motion of the car caused the front seat to fall back on top of me whilst in flagrante.
Happy days!
