You should test ride one, or better, a few of them, see if any "speaks" to you. That's how "they" got me hooked to buy the first one! And if you look at used ones, although they were so far all produced at low volume so as some are almost unique, Guzzi's aren't usually known for their resale value (unlike other brands we know) - so luck would have it you'd run into some truly great deal.

They are like wine, get better the more time you own, ride them, get to know their quirks, and wrench on them. They're kind of a hands on approach - not too difficult to work on at all - but require just enough to make you put effort and create that true bond. Don't listen to me I'm just on my second in three years and already have near 100,000 miles between the two and plenty stories to tell. But if you want to ask any question on Guzzi's, let me know.
