there weren't as many cars and there wasn't nearly as much variety in terms of livery. They were all raced red. Sometimes with stripes. And although they are thought of as 64 and 65, there was only one car that ran in any significant races in 65, outside of Italy. None in the U.S. Ferrari started running the 275 GTB Lightweight in 65 which would make a good model as it won the class at Le Mans. Not holding my breath though.
