I went to my local Canadian Tire (insert your local cheap bike store here) and bought a black bike mirror for $4.99. The threads needed to be extended to be long enough to go all the way through the hinge; the diameter was a bit small so I wrapped some plastic strapping around it. At 75MPH I can see fine, maybe not the clearest image (it's not a glass mirror) but surely enough to see other cars.

I looked at almost every post on here looking for good mirrors and wasn't satisfied that any available were any better than my bike mirror. I'd love a set that I could relocate and leave the ones on the doors off, but they all seem to have downsides - like not being able to see with the doors on.

 

Got one of the QD I mirrors for xmas last year. works fine for what it is, a bit bouncy, but not too bad. If I had been spending more time on here before I got that one I would have just picked up the motorcycle mirrors and have the $$ saved for other mods for the xmas list hehe.
