There it is: the Aisha garage kit from an honest seller, taken out of its box to show that indeed the parts are there including the ponytail which was the missing piece of the puzzle. I'll send an e-mail to Carlos soon to give him the update and hopefully he'll be receiving a ponytail in the post soon enough. (Or the whole kit, not sure.)
In case you're wondering, the other items in this box are Takeshi's Castle merchandise, my favourite Japanese game show from the 1980s. (Items look quite immaculate, all things considered.)
So, I'm happy about this of course...
