Well, it really depends what you're planning to do with it. If you're looking for a bike to restore, maybe this isn't it. If you're looking for a bike to turn a few wrenches on, maybe this is it. It'd be a great starting point for a project, a bike you can make yours without having any reservations about "ruining a classic" that bike's classic days are over, it's a rat, a hot rod, a prime learning experience. How many members have only one CB? It probably won't be your last.
Go for it.
