dude have you been in a classic mini? its literally a coffin. that being said i like trying to drag race mustangs in my buddies one. Check out Kei Cars in Japan.
A coffin that fits 4 adults and a German Shepherd in the estate bit. That's quite snug, but no worse than a Polo, Beetle, Fiesta or 2CV of similar era.
But like most cars it spends most of its time carrying just one or two adults, maybe a bit of shopping, when it has ample room.
I personally know of someone that suffered permanent short-term memory loss from a terrible crash in an original mini. A woman pulled out in front of him without looking properly, his car was pretty much completely destroyed, and he was lucky to survive. It's all well and good to praise their size and practicality, but they come at a heavy price.
In the same era few cars would see you better off. A Polo or Escort would be similarly totalled, a big Merc or Volvo would often happily demount the engine and punch it back into the cabin taking your legs with it...
