I've been looking into the smart deal with Liberty Mutual at that website above.
As it looks right now, depending on when I get mine, I might roll my VUE over to them and go for there. I have been very happy with Progressive, but if they try to stick it to me with rates for the smart, I'll walk and take all of my business elsewhere.
From what Liberty Mutual quoted me regarding the smart at full coverage, 100/300/100, and the VUE as liability only (due to age and mileage), Progressive is going to have a hell of a deal to try to beat.
