Thanks for the kind words @rauljara. I do indeed love Zipcar and as I mentioned I gave up my personal auto for the service. I'd say the percentage of "bad experiences" for my usage is probably less than 10%, but it is significant enough that you should know that if you become a serious Zipcar user you will run into bad experiences more often than you might think (and they never come at a good time...)
