What a Fwit!! I would love to inspect it & see what i could fault. Apart from the plate lamp, I bet i could find others.
Does look a nice car though.
Re reverse camera - retrofitting one is NOT a hack as such. There was actually an OEM option available too. That said - the aftermarket option is probably better being that its later technology. I am reliably informed this is the case in regards to the E70 OEM v aftermarket.
