This car marks Holdens transition from a 25 year old carby to the electric/efi engine system. Holden totally screwed it up with the VK, that is why they used a Nissan engine in the next model, the VL.
The electrical system on the VK is totally crap, people have told me to replace it with the one on the previous model (VH). This also makes it hard to find causes of problems, like pinging.
It drinks petrol like there is no tomorrow, even more when driving around the city, I can sometimes get around 350km with a full 60 liter tank!
If you are going to get the VK, get it with EFI or the 5 liter V8 (not the 4.2 liter), or get a cheaper & more reliable VH.
But it is the best looking Holden, it is cheap to repair and easy to find second hand parts, since most of them end up at the wreckers. It also has plenty of power.
Vn holdens are the best one most power 4 your money next best vk and vh are very good to vl no good...3.8l is the way to go some problems, but that eng are very good best in the world.
