HSV Problems

I think you could be looking in the wrong area. U2105 is an engine fault code, which perhaps helps explain why it comes on under heavy acceleration or travelling uphill. I would have a diagnostic check done on the car to see if you can better home in on the cause of the problem.

HSV produced 500 SS Group A versions of the Commodore in 1991 to homologate it for racing, i.e., Bathurst. It sounds like one of those, maybe built after the introduction of the VP in September 1991.

I don't expect the prices to change much in the next 5-10 years, but in the longer term I think the HSV GTO will become a much sought after car. Look after it and keep the kays down as much as you can.

The price is higher than average for a 2005 Grange, but the kilometres of the car you're looking at are less than the average.

On the surface it seems a good buy if it is a genuine HSV Grange and the odometer is correct.

There's not a lot that goes wrong with them, so focus on things like condition, which is paramount in an older car, and servicing is equally important.

Depending on the condition, service history, and past use it would be between $9000 and $12,000.

It’s an old car, it’s a headlight, which I doubt is covered by the warranty, so just replace it and get on with your life.

The average price of that model is $10,400-$12,700, so the quoted price is a little high. But against the kays are lower than average for that model, and the boxes for condition and service history are ticked. If it appears to have been well looked after by a caring owner, hasn’t obviously been thrashed it would seem to be a good choice.

The VN Group A was a special run of Commodores to homologate the car for racing. They’re now collectable and worth $37,000-$45,000 depending on condition, kilometres etc.

The trade values them at around $8500, but the collector car market operates differently to the regular used car market. The value comes down to what someone else is willing to pay for it, its condition, odometer reading etc. The chances are that in the long term it will hold its value, and maybe increase. If you’re looking at it as an investment then park it, cover it up, and drive it as little as possible.
