I had purchased the convex style mirrors from Sierra Madre.

I thought Paid too much for them, but I figured one sideswipe of another vehicle and I would be cussing at myself for ever.
Overall, the quality of the convex is good. The mirror surface is convex, but not radical like a stick on spot mirror. You really dont see the convex unless you look for it. The field of vision in my blind spots are greatly improved.
My everyday driver is an econoline van/surf wagon. I sit high and can see for miles, and feel safe. The speedster had too many blind spots.
I guess it is cheap preventative fix in the long run.
I would like to find a convex rear view mirror for the front post. Has anyone found one?
I will continue to let the ebay auction sell these for me.
