I HAD Progressive a while back. I got rid of them because like so many other companies, the first thing they do is start in with the whole deal of, "If we had your house as well as all of your cars we could save you even more!". I'm tired of playing that game. I did that and within a couple of years my rates had crept up beyond any initial savings I might have experienced.
I dropped them after they refused to budge on lowering my rates. I drive very little and never had a claim with them. I now have Hartford through AARP and the savings are substantial. As far as the AARP being anti gun and all of that, I really don't think they are anymore than hundreds of other companies who are accused of much the same thing. It almost becomes an impossibility to keep track of these type of accusations with any reality or certainty.
If you examine these lists put out by the NRA and similar pro gun organizations, it changes almost on a monthly basis as companies go on, and drop off such "lists". For example, there are several companies who are put on these lists by comments made by management personnel who no longer work there. So you have to be somewhat realistic about it when you make decisions on who to deal with. If I'm not mistaken, Progressive's President is supposedly a big anti gun guy.
