What are the next collectables? What should we keeping?

My mate has a 2001 senator with 20000 km on the speedo he bought it new drove it for about 2 years then just parked it
would this be worth $$$$ in the future

i would think so but he probably paid a lot for it, when did we get the GST? i always thought the HSVs got a bit ugly after the VS they were too chunky and over done for me but the VZ senator was nice
