Here is a link to the Russkie copies of <BR>american cars. Note the resemblence of some of them to the legendary Buick 8 models.<BR> <A HREF="http://www.abc.se/~m9805/Oddcars/gaz/picture_eng.html" TARGET=_blank>http://www.abc.se/~m9805/Oddcars/gaz/picture_eng.html</A> <P>One more link. Note the comment on the brakes, " apply brakes in moscow to stop in vladivostok !!!

I gather the key is in the way these are manufactured that makes it all worth while!<BR><p>[This message has been edited by Paul Lakowski (edited 06-08-2001).]
