(I never have; the one car I ever drove regularly handled great but was pretty underpowered, so it felt like a big accomplishment to speed ever-so-slightly.) (Where "ever-so-slightly" occasionally included 2.33x the limit on certain Jamaicaways I will not mention by name.) (But I digress.)
It can be packed very efficiently with lots of small cargo, but isn't really viable for moving furniture---its shape had deceived me, but it is actually quite small.
If today I got a job that required a car but was within reasonable commuting distance of the city, I would buy an xB.
The Civic I got last week was quite good too, but I still feel that sedans are just never very good city cars: they take up too much space in proportion to how much stuff you can put in them and how much visibility you get.
Next in the queue to try out: a Honda Fit and a Yaris. (That commercial where they spit on each other is just so precious.)
(I remain a huge Subaru fan, but specifically for recreational driving, which is a habit I have firmly kicked. I will probably never buy another Subaru.)
