I've got 2 Be-1's (both canvas roofs) which I bought for $900. They're at my house in Brisbane currently. My red one just needs it's brakes sorted and should be roadworthy, my other white one is completely rotten so used for parts.
Another guy visited me at my place one day and says he has one sitting in his yard around my suburb. Not sure on that one however.
I know another guy in Adelaide has a yellow Be-1.
