I am fortunate to have purchased the BV from a large Vespa/Piaggio/BMW/Ducati/Triumph dealer near here. When I ordered the replacement turn signal stalk I talked about earlier, the parts guy told me that delivery time tended to be slow, compared to the other makes they sell...parts availability is evidently not a big problem, but slow delivery response can be.
The other part of the equation is...how often will replacement and repair parts (anything other than routine maintenance parts) be required? As I said, the BV500 and BV250 series machines have a good reputation for reliability and long life...
I guess we'll find out...I'm on a learning curve here and I'll let you know how it goes.
