Relo questions: Flexcar

Here’s the first in a series of questions related to my move to Seattle.
I’m thinking about going car-less in Seattle, and relying on Flexcar when I actually need a car. Public transportation seems pretty good, and I may well be able to find an apartment in walking distance of work. Advantages: no garage or parking costs, no anxiety about car theft. (Chris seemed to have particularly bad luck when he lived in Seattle.) Disadvantages: less flexibility, can’t drive outside the lower 48 (i.e. no trips to Vancouver or Victoria).
So what do you think? Right now I’m planning to leave DARWIN in Massachusetts; I can always change my mind in a few months….
