Club Car manufacturers a DS model golf cart. The DS 2000+ designates carts manufactured in 2000 and newer.
There are some differences between the DS 2000+ and the DS Pre-2000 models.

The best way to determine if your cart is a DS 2000+ is by looking at the roof struts. The roof struts for the DS 2000+ are black and the roof struts for the DS Pre-2000 are aluminum. Also, on the DS Pre-2000 there is an additional windshield support that connects the windshield to the cart body. The DS 2000+ does not have this additional support.
