t3488g, a word of advice (and a proverb, i believe):

here is the link to the Achtung Panzer page
http://www.linux-penguin.org/achtungpanzer/cars.htm

there are two on ebay right now.
one quite reasonable w/ one bidder,
one very high w/ no bidder
(search "1/35 tamiya 8rad")
and of course, on in my closet. :-)
