Welcome to the forum. VStar made some great bikes, i plan on keeping my 650 till the motor falls out, and looking at getting a 1300 or 1600 next summer.
At the risk of being the bear of bad news: are you aware that yamaha has dropped the entire Vstar / cruiser bike line?
Those of us that have bikes will mostly keep them for a long time, but if you are just getting into cruiser hikes, Honda and Kawasaki make some excellent bikes too, nearly as reliable as yamaha. Suzuki and HD have some reliability issues in the long run.
The only reason i bring this up, you will put a lot of yourself into the bike you get, and you may want to consider a path that will allow you to buy a new bike in a few years. That is the one thing you cant get anymore: a brand new Vstar cruiser.
The flip side is, you should be able to find a low mileage Vstar 650 for a few thousand dollars for the next few years at least.
