its a tough debate on this topic - it's nice to think about our cars appreciating in value to help offset the money poured into restoring them, but it cuts both ways when they become too expensive to buy in the first place. one of the things i love about my z is how affordable it is to work on, which makes it much more enjoyable to drive every day. as exciting as it would be to have a piece of euro exotica in the stable, i don't think i'd be able to drive it to work, park it at the grocery store or (gasp) put the dog in it... sorta leaves the realm of sports car and becomes high-end investment art. not that i'm seeing that any time in the near future for my z, but its the trend in general i'm commenting on.
i've enjoyed building a couple of ducatis and after getting used to the ridiculous prices they charge for tiny bits of sculpted billet its quite refreshing to see how affordable a z and its parts are.
i also thoroughly enjoy the unpretentious, down-to-earth crowd around the z. i've met a lot of great folks - tinkerers and clever minds that don't cringe at the thought of modifying, swapping parts around or fabricating your own pieces out of scrap. i believe this is directly related to the fact that owning a z hasn't become a big statement of net worth.
the part i like least about ducatis is the "lifestyle" crowd - clad in thousands of dollars worth of branded gear with thousands of dollars worth of shiny bolt-on bits on the latest model, with 500 miles on it after 2 years and 3" chicken strips on the tires. and of course they're the ones who will shake their heads when i pull up with a fairing plastered with bugs (because i ride it) and gape at the fact that i put a suzuki front end on my ducati (1/3 the price and works way better).
ok, rant over...
