I agree with HSV Commodores not being worth much apart from VN GroupA and maybe the 427ci versions, probably because they are seen as a Commodore. The HSV coupes, particularly the GTS and Coupe4 are the only ones i'd have and prices reflect that they are sought after. You can buy HSV VX Clubsports for around $10k in great condition, $5k cheaper than the equivalent V2 CV8 Monaro in the same condition and kM. A nice VX GTS is $15-$20. You won't buy a V2 GTS (equivalent of VX GTS) for much under about $35k or a Coupe4 for under $45k.
