I absolutely love convertibles, and don't understand how I missed this when it was new (perhaps because I don't live in Japan? but still).
a couple of things stand out to me:
1) that's a huge amount of space used for storage of the top - a vertical storage with a little more folding would likely have made better use of the space
2) I would love to see something like this in an electric, but doubt I ever will - something of this era and features could likely never pass modern safety requirements (yeah, I know about the nobe 100, but it's not exactly a car)
regardless, it's nice to see so much attention to detail that seems to be lost these days with modern cars.
