Wow... $12000! That IS impressive.
You know, in 1991 when I first came to Canberra, I was into road bikes and not at all interested in old dirtbikes beyond a sort of 'wow, lookit that'. I remember that the local Suzuki dealer here had a section down the back for all the old dirtbikes he couldn't shift. There was a battered old 82 XR500, a few nondescript things I can't recall, a Montesa of some sort, and a reasonably tidy KX450. I remember checking it out cos I had never seen one before, all I could recall of them was a DirtBike test where one had shredded its rear wheel. I thought it looked great. I think they wanted a few hundred bucks for it. Hmmmm... if only I knew then etc.
Keep posting pics of that A5 Ajay, that is beautiful.
