Both used the 6C&#8217;s independent suspension but in shorter wheelbase than the production cars.<\/p>\n<p>Three or four coupes were made by Colli for the 1953 Mille Miglia. Despite competition from Lancia and Ferrari, one of these finished second overall. Later the cars were brought to Le Mans were they recorded the highest top speed of 154 mph down the Mulsanne. Unfortunately, all three cars retired.<\/p>\n<p>After Le Mans almost all the Colli Coupes were rebodied. One was fitted with a Zagato Coupe for Joakim Bonnier. Another was send to Boano for a new body and gifted to Argentinian president Juan Peron. A third was bodied by Pininfarina into the Superflow concept car.<\/p>\n<p>A few spiders were also built by Colli for Alfa Romeo and one of these won the 1953 Supercortemaggiore at the hands of Juan Manuel Fangio.<\/p>\n<h3>1953 Alfa Romeo 6C 3000 CM Gallery1953 Alfa Romeo 6C 3000 CM Gallery<\/h3>\n<p>See full <a href=\"http:\/\/www.supercars.net\/blog\/1953-alfa-romeo-6c-3000-cm-gallery\/\">1953 Alfa Romeo 6C 3000 CM Gallery<\/a> here<br \/>\n<a href=\"http:\/\/www.supercars.net\/blog\/?attachment_id=190101\"><img decoding=\"async\" class=\"aligncenter wp-image-190101 size-thumbnail\" src=\"http:\/\/supercars.net\/blog\/wp-content\/uploads\/2016\/04\/1953_AlfaRomeo_6C3000CM2_small.jpg\" alt=\"1953 Alfa Romeo 6C 3000 CM\" width=\"\" height=\"\" \/><\/a><\/p>\n<div class=\"copy-paste-block\">\n<p>1361.00127-1953 Colli Spider.
