I used to love driving too. Well, I used to love driving fast (as in speeding) on almost empty roads. Since there isn't much opportunity for that any more, and especially not in Spain, unless you have limitless funds to pay the fines, it isn't so much fun now.
My partner has driven the car once, I think, in the 2.5 years we've lived in Spain, but she doesn't really want us to sell it just in case she decides to drive it one day. Really. I just can't be bothered with driving unless I absolutely have to, so it really seems pointless to keep paying over £300 a month (in finance, garage fees, and tax, insurance, etc) just to keep it sat in the garage. Even if we weren't left with much of a lump sum once we'd paid off the finance, the monthly saving would be significant. (It wouldn't be long before I could afford to buy one of those ICE recumbent trikes I keep drooling over.)
It is a big decision, though. I passed my test in the same month as my 17th birthday, and have owned a car ever since. The thought of not having one is a bit hard to get my head around.
