You are being a bit harsh on distance acheived with some of these antenna's Towerdog. For example, I have a 30 inch centre loaded antenna on my tractor at work and get an average of about 5-8 miles with it on a standard 4 watts rig. On my car I have a Red devil base loaded antenna on a 7 inch mag mount and I'll get 8-10 miles comfortable on 4 watts. In fact I talk regular to breakers 14-20 miles away but that is subjective at times. Wilson work well also the Sirio base loaded stuff works particularly well. Best place is in the middle of the roof with preferably a triple mag mount for added security. I wouldn't recommend putting it on a bumper, a mirror mount or anything like that. You will have trouble with VSWR because you are relying on the earths between bumpers and the car, mirrors etc to get a good VSWR. Then they have the added problem of becoming directional. Roof mounted antenna's are also directional usually from front to back of the car but its something that we all live with and its not too much of a problem. Roof mounting on a nice magmount will get you the best performance without any shadow of a doubt and if you knock it off by accident, you can just put it back on.
Edit: Also for serious offroading consider the springer type but with a 5-6 foot whip and a triple mag mount, you can get those horizontal going under trees and they just spring back to their position. People mentioning VSWR at ch1/40 at 3:1 is just unacceptable in my book. Roof magmounts VSWR wants to be 1.3:1 on ch19 and no more than 1.8:1 on ch1/40. High VSWR will reflect on performance significantly while mobile.
