I guess I am spoiled by having two mirrors on my newer cars.
My driveway is very narrow and I need a right side mirror to park into my garage,and to paralell park downtown.

I was taught to back into my parking spaces--not drive in.So a right side mirror I feel is necessary.

If you get a correct looking mirror,use it for what it is and not worry about what others think
Plus it may save some embarrassment and avoid any boo-boo's
