Well, it seems seems the addiction continues - I've committed to buy this car, and hopefully will get it transported to Canberra early next week. Was purchased sight unseen, but thanks to BenzBoy and his mechanic at Autohaus Strecker am fairly confident that I know what's wrong with it. Cam2 has also been doing some digging, so thanks for that also.
There will of course be pictures when it arrives. Plan is to work on it (as well as the blue 6.9 and the 350 and the garage itself) after I get back from o/s, and posibly pass it on to Cam2 after "SELfor50 stuns Stuttgart" happens sometime next year.
The gold exterior sounds OK, but the tan interior scares me too - this was one of the reasons I passed up Mercules' 450 - I just don't like that colour. Maybe it's because the inside of the Crumpledoor is tan. Gold-on-tan especially sounds a bit wierd. Anyway, we shall see.
