Bicycle mirrors (Schwinn, I think) purchased for $5 each at Canadian Tire store. Installed with a pair of pliers and a Phillips screwdriver (to tighten the mirrors) in less than 5 minutes (added a couple of flat washers. Good visibility. I had to mount the passenger side one on the lower hinge because the dash obstructed visibility -- some tricky angling of the mirror, but surprisingly it actually has better view than the drivers side. Zero vibration and don't start to fold in until over 140 km/h. Took the doors off for the first time about a month ago and they are not going back on until the fall -- doors off is the only way to go!!
