Your journey seems remarkably similar to mine.
I bought two zeds in the space of nine months and was so smitten with them that I honestly thought I'd never sell up. My dream was always a Lambo however, and when the opportunity came along I had to do it. At the time I was late 20's, unmarried and no kids.
However the onset of the credit crunch mean't that having all my money tied up in a car made zero sense at all. Then I got married. Then I had a kid. Then I had another and now I can't get the Mrs back to work!!!
Like you, I'm also considering getting back into a zed, probably more as a hobby rather than anything else as I work from home so don't actually need a car at all. I just want something clean, drive to football in and buy mods for that I never bother to fit and flog on here for half what i paid for them like I used to
