Used Holden Commodore review: 1978-2003
By Graham Smith · 19 Aug 2003
The Commodore is turning 25. Graham Smith tells you what they are worth today as used cars.  The first Commodore was smaller than the previous Kingswoods but boasted European running and handling gear. It topped the sales charts and was Wheels Car of the Year for 1978. Poor build quality and rust problems make it difficult to find a VB in good condition today.  A facelift of the VB with updated six-cylinder and V8 engines. For the first time there was a four-cylinder engine available but it was disappointing.  A smart new shadow tone two-tone paint scheme was available for the first time on the SL/E and made it even more attractive.  But build quality problems and rust plagued the VC; it's hard to find cars in decent condition. Another facelift of the first Commodore, the VH had more engine upgrades.  With Holden's ongoing build problems, including poor paint, good quality VH Commodores are hard to find. Values range from $600 to $3400.SS was introduced as a limited edition model and remains the most desirable. Be careful of cars that have been thrashed. This first major facelift featured louvred grille, plastic bumpers and new rear quarter window. New models included the Berlina and the luxury Calais. The four-cylinder and the small 2.8-litre six were dropped and the 3.3-litre became standard.  The 4.2-litre V8 was dropped, leaving the 5.0-litre as the only V8.Performance models, the SS and SS Group 3, were built with Peter Brock's HDT operation and are the most collectable VK models, along with the SS Group A which was designed for the new Group A touring car racing. New front and rear treatment, new slim headlights and a lip on the boot lid were features of the VL.  The Holden six, a faithful servant since 1963, was replaced by a Nissan imported 3.0-litre six, prone to over-heating and head damage.The V8 was replaced by a turbocharged Nissan six which put out 150kW, until public protest brought the V8 back by late 1986.  The VL SS Group A, finished in Permanent Red, is highly collectable today.TWR became Holden's performance partner in 1988 and their first creation was the TWR VL SS Group A, better known as the Batmobile for its wild body kit.  The VL is popular with young drivers today but be wary of cooling problems with the Nissan engine. The Commodore was being soundly beaten by the Ford Falcon in sales. Holden responded with a bigger car.  Power came from a fuel-injected 3.8-litre Buick V6 with an optional 5.0-litre V8.The SS is a popular model, while the Durif Red SS Group A is the most collectable.  However, cut-price engineering and poor build quality mean lots of tatty VNs now. A facelift of the VN with attractive styling changes. The V6 was refined and the 180kW HSV 5.0-litre V8 became an option over the standard 165 kW V8. SS is popular for a sporty ride, with the Calais a popular prestige choice. With new front and rear sheet metal and new head and tail lights, the VR was an attractive remake of the VN/VP.  Holden introduced driver's airbag standard and ABS and IRS available across the range.  SS and Calais remain the most sought models but the value-packed Acclaim is a popular family car.The new 3.8-litre ECOTEC V6 engine was smaller, lighter, smoother and more fuel efficient than previous.  A passenger's airbag, and improved remote central locking with an immobiliser, were added. The third all-new Commodore struck a decisive chord with buyers. It was longer, wider and had a longer wheelbase and roomier interior with more legroom and width than any previous Commodore.  The American Gen III V8 replaced the Aussie V8 in the 1999 Series II update.Generally without major problems, although the Gen III V8 has been plagued with oil consumption and piston rattle problems. Styling changes were minimal but the V6 now had 152kW and better fuel consumption thanks largely to new electronics, and the V8 was up to 225kW, courtesy of a higher flow inlet manifold and new fuel injectors.Changes to the front suspension produced more progressive steering, which aided handling. Rear suspension improvements make VX II the better choice. The jury is out on whether the VY, with sharp edges and hard lines, is an improvement on the VT/VX. Revised steering package delivered more handling improvements.V8 power jumped to 235 kW and was standard on SS and new SV8 sports model. Auto transmissions were refined.  VY will continue to roll off the production line until the VZ is launched in 2004.

Generation noisy
Answered by CarsGuide team · 14 Nov 2003

You're right to be concerned as there are lots of reports of problems with the Gen III engine. You're also right they can use oil at an alarming rate, and they can have a piston rattle. Holden has rebuilt lots of them under warranty, so I would ask the seller about any work that has been done on the engine. Ask for proof positive that work has been done if they say it has. Ask also for any records of oil consumption they might have kept. It's impossible to tell if an engine is using oil simply by looking at it, so you have to try to get as much info out of the owner as possible, and hope they're telling the truth. Check the service book for anything that might say it's been in for extra servicing, or had additional oil added. As for the noise, listen carefully for a light metallic rattle as you blip the throttle. There's no need to rev it hard, simply blip the throttle and you should be able to hear it if it does rattle. Keep it in the back of your mind that there are plenty of cars out there, so if you have any doubts about the car you're considering, walk away.

Power of commodore
Answered by Graham Smith · 10 Jul 2003

The change took place with the VX in 2000. The increase in power is predominantly due to a more powerful electronic control module that could process more data more quickly, and a new smoother intake manifold that improved the V6's gas flow and volumetric efficiency.

Trailing behind
Answered by Graham Smith · 19 Jun 2003

Early Commodores with independent rear suspension suffered from high tyre wear because of geometry changes they went through as they worked. Anything that made the rear lower, such as putting the weight of a trailer on it, made it worse. So the advice you received was correct and you would have to replace tyres more often on a Commodore built before the VX Series II. The VX Series II saw the independent rear suspension improved with additional links to particularly control the changes in toe-in as the wheels moved up and down. This meant Holden could change the suspension settings which reaped benefits in tyre wear, as well as worthwhile improvement in ride, handling and stability. If you are looking to buy, then I would recommend the VX Series II, but if you have a car you want to improve, then take it to a suspension specialist who will be able to suggest ways to solve the problem.

Bathurst specials
Answered by Carsguide.com.au · 28 Nov 2003

There's virtually no similarity between the Bathurst racers and the road cars you and I buy from Ford or Holden, apart from a vaguely similar appearance. The engines are purpose-built 5.0-litre V8s. Neither Ford nor Holden have a production 5.0-litre V8 on sale. The gearboxes are purpose-built for racing and the suspensions are special, as are the brakes, wheels and tyres. The bodies may look like the production equivalent, but they're specially built, incorporating roll cages and other reinforcements. And get this: the Commodores now run a Falcon-type wishbone front suspension instead of the MacPherson strut the production cars run. The Commodore racers have long-run Ford nine-inch diffs as well.

Holden Commodore: Trouble starting engine
Answered by Graham Smith · 25 Sep 2003

We contacted Holden for their response, which is: ``While it is impossible to diagnose a car without sighting it, rough running on start-up and/or hard starting can be caused by many things, including leaking injectors, carbon build-up on the valves, etc. Injectors wear over time and are also subject to deposits from the fuel. Given the age of the vehicle, injector leakage is a possibility. This is not a generic V6 problem. If the injectors are in fact leaking, this is a maintenance item. Injector leakage can be tested by carrying out a pressure test and confirming pressure drop.'' I think this is good advice. Take the car to a fuel-injection specialist and have them check the injectors, and think about having them cleaned.

What to use once Lead Replacement Petrol is phased out?
Answered by Carsguide.com.au · 23 Oct 2003

The Commodore will need an upper cylinder lubricant added to the fuel if you run it on ULP. The Toyota should happily run on ULP without any additional lubrication.

Worth the money
Answered by Graham Smith · 25 Sep 2003

On the surface it sounds a reasonable deal. You would expect a VT to have done 90-110,000km on average, so the mileage is below average. The trade is paying $11,000-$13,500 for a VT S at the moment, and retailing them at $15,000-$18,000. Check the car thoroughly, and make sure the odometer is correct.

Backfiring blues
Answered by Carsguide.com.au · 19 Jun 2003

Since you have covered the basics of fitting new spark plugs and leads, I'd look deeper. It sounds as if you might have a burnt valve so I'd suggest you get a mechanic to do a compression test on the engine and look for a cylinder that is not holding compression.

Time for an upgrade
Answered by Graham Smith · 10 Jul 2003

It's certainly worth upgrading your brakes to the later VT set-up. You will improve your braking performance. As far as the shocks go, it's worth fitting new ones. Shocks are a most important safety item in your suspension, and there could be ride benefits as well. I would suggest either Koni or Bilstein shocks, though they are more expensive than the Monroes.
