I found that with the original (optional) passenger-side mirror with the convex center added, that when looking straight ahead I would pick up vehicles in my blind spot with my peripheral vision. Combine that with the 5 window cab and you've got a better picture of what's going on around you than with the majority of new vehicles. It may look a little strange all twisted up, but it sure helps in heavy traffic. Haven't run over a Mitsubishi since I put it on......on the passengers side.
