I would love them but sadly can't afford them.
I still think fender mirrors are legal reading through some of the ADR's
15.2.3. Adjustment
15.2.3.2. The exterior mirror situated on the driver's side must be capable of being adjusted from inside the vehicle while the door is closed, although the window may be open. The mirror may, however, be locked in position from the outside.
15.2.3.3. The requirements of paragraph 15.2.3.2. do not apply to exterior mirrors which, after having been knocked out of alignment, can be returned to their former position without the need for adjustment.
That last bit to me reads that as long as its a spring loaded fender mirror that goes back into position when hit (which i believe these are) then they should be sweet. Also in the positioning section it mentions they must be placed either visible from the side window or through a section of windscreen that is swept by the wiper blade.
