VF hasn't been (yet) but near everything else in the Holden range is. The Malibu is just beyond woeful. Cruze & Colorado are the real problem for them. The current Cruze is a good car but oldest in it's segment by a long way yet the replacement is still a year or more off and reports are the upgraded drivetrain even longer. The Colorado is even worse. Less than a year old and not even close to market leadership to the ancient Hilux/Triton and well behind the dynamically superior Ranger which is hampered by supply constraints.

The VF hasn't been discounted yet because it was heavily reduced in price when released. Remember the articles that pointed out the RRP on the Evoke was $5,000 below the RRP of the last VE Omega? It was one of the strategies employed to kick start and promote VF sales. With reductions like that from day one, there can't be much fat left to cut when discounting as time passes.
I think Holden is paying the price for some very poor decisions during the early part of last decade. The VE was seen as the natural successor to the VT-VZ, when it should have been a completely different class and size of vehicle altogether. Replacing the European based smaller cars with Daewoos has never worked at any time - every single Daewoo based model has been a poor performer compared the competition from other Korean manufacturers. Not one Daewoo model has been better than the European model it replaced. All because Daewoos could be sold cheaply here and bugger the quality. It's been a dead set list of duds.
the just superceded Barina (formerly Kalos, which was a dog). Replaced the XC Barina, a brilliant if Spartan car that won car of the year in 2000
Epica, (only appealed to the over 70's). Replaced the Vectra, which was vastly superior on the road and in appearance IMO.
early Cruze, which needed huge input from Holden to sort out, but too late.
Barina Spark (who the hell buys those things, anyway). Replaced the billy-cart, but the billy cart was much better.
Malibu (which might have been a Chev design, not sure). Replaced the Epica, so it has to be an improvement.
the latest Barina (better, but being done like a dinner in the marketplace).......
Viva - another recycled obsolete Daewoo that flopped under its original name of Lacetti, so, like the Barina, it was re-released as a Holden and sold just as well as it did when it was a Daewoo.......
The only one that has enjoyed sales success is the Captiva (drum roll, please), but it is now very old and very inferior to its competitors. It sells on great price and value but little else.
Not one of those other cars has been reviewed favourably by motor mags and every one has been inferior to the cars they replaced. Is it really any wonder that Holden is in the position it finds itself today?
