At this point I've featured a lot of classic Minis, and they pretty much all seem to live in San Francisco. What's easy to forget about these little cars is that while they look old, and the basic body dates back to 1959, these cars were built for over 40 years. The last "classic" Minis were rolling off the line when BMW was gearing up to build their all-new MINI Cooper for the 2001 model year.
Getting A Little Psycho on Tyres!, a pretty knowledgeable car enthusiast in his own right, said he had never seen or heard of one so equipped. Perhaps it didn't get hot enough in the UK to offer A/C? Oddly enough, automatic transmissions are also fairly common on these later cars in Japan. Lending further evidence to suggest this car came from the Land of the Rising Sun are the right-hand-drive configuration, retrofitted fender mirrors (note the original mounting location on the doors, thanks Art for pointing that out), orange side marker lamps and last but not least, an official-looking kanji sticker on the right rear quarter window. Curiously, the importation rule for foreign-market cars is usually 25 years. I wonder if there was some loophole that allowed this Mini to come over early. The plates are fairly recent.
