Towing mirrors for x3 2021

Previous threads say that EMUK in Germany sell extension mirrors specifically for that (and other cars) . Google will give you those threads and a contact to order from source. But expect about £100.

Anyone got a BMW X3 caravan mirrors EMUK for sale

Try the "Suck it and see" Deluxe mirror. I am using these as an alternative to the Aero grand and much prefer them. 

I've been using the suck it n see for years, had the odd one loosen and hang down the door swinging about on its safety cord. I've just ordered a set of emuk for our xc90 as the suck it n see sit very close to the mirror frame limiting adjustment..

seen a set fitted to an x4 last week and was very impressed.
