Thanks for the TL
I know it's manga but I just like thinking about cars
I'd bet you can count the amount of street-driven Countaches in Japan on your fingers*, two of them randomly meeting outside of car shows would be astronomically rare.
*There are less than 2000 total, Japan likes 'em, but prolly only about 150 in Japan, including unregistered. Like twenty showed up to a massive Lamborghini-sponsored event, and rule of thumb for exotics is 75% are locked up by rich guys so that checks out.
Most of the time 75% of the remaining are only for show and track, so I'd say comfortably a max of 10 are ever actually driven on roads like you would a Miata.
