Computer addiction - I just love getting, building, installing, configuring laptops and PCs. I have 3... 4 laptops (2008 netbook, second hand 2005? iBook, 2011 Dell Vostro, second hand 2008? Dell Latitude), a desktop (gaming), Playbook, iPad (which I hate but actually I use that for work - testing websites), etc, etc.
Bought a Crown Victoria about 3 months before I needed a car at all, and.. well, it's a Crown Victoria! (In my defense: It cost less than $3k, and I'm getting a hitch on it, and I managed to get 8l/100km on the weekend which is pretty amazing - 'ideal conditions' obviously!!)
