Difference between 2004 and 2004.5 Club car DS

[jasonbbates]

Hi I just bought a used Club Car DS and thought I was getting an 07 Model. When I looked up the Serial Number and found out it was a refurbished unit from the factory. The factory serial number starts out with 7G07XXX. Which is a Silver Standard Handyman IQ. I did not notice that the sticker was on top of the original serial number sticker so I peeled it off and under it was the serial number AQ04XXXX. So I have two questions that I hope someone can please help me with. Is there a huge difference between a 2004 and 2007 and what is the difference between a 2004 and 2004.5 model. I have seen this when I have looked for a lift kit from Jake's lift kits. Also how do I tell if I have a 2004.5 or later mode. Thanks a ton in advance for the info.
