What are you suggestions?
If you know what aspects of your site are strong, I would suggest leaving them alone, i.e. layout, content, navigation, etc. However, simple improvement like a font or color changes or maybe newer graphics may make a huge difference in it not looking like 2004.
Of course, I'm from the old school of "if it ain't broke, don't fix it."
