If you need a fairly decent outside rearview mirror, I would suggest these:
I have used them om my Sport Trac for the last year. If one follows the directions, they work excellent. When you install them, be sure your standard mirrors are clean and make sure the clips on the CIPAs are "flat". This is where the negative reviews come from.
Best part, Amazon has them for $18.00 down from $44.00. I do not work for CIPA nor Amazon. Just suggesting a product that has worked for me.
BTW, that is for only one mirror. You will probably need two.
