I think HSV Senator and GTS models will become collectable and also cars like VZ SSZ that they didnt make many of. I used to walk straight past the commodores at GM day but now its interesting to see what people are buying just for a weekender.Last year there was a few VN and VP SS commodores,low Ks and in mint cond and another one that caught my eye was a VS V8 Berlina wagon (not sure if it was factory V8) but if it was it would be quite rare.We have just bought an ex police V8 VS and they are stamped police on the build sheet and also has BT1 on the compliance plate so maybe in years to come the EX cop cars may become collectable.
