Bro every jdm's side mirrors, cabin panels, dvd screens are hot cake to thieves. Sad to hear about your loss, when I got my Passo, even it's side mirror got stolen and I remember how upset I was, but then I realised that we get the cars for ourselves but the side mirrors in these cars belong to thieves lol.
-Btw I got side mirrors of an old Jdm corolla they are full metal side mirrors, thieves cannot break them, I just had to get a matching paint and got them coloured. And they're powered and perfect.
