There would still seem to be a problem with the crank angle sensor. The symptoms suggest it, and the diagnostics back it up. Having replaced the sensor without solving the problem you need to look at things like the connector and the wiring that leads to the sensor.
Consulting a brake specialist, like Howard Reynolds at Race Brakes, is always worth doing. Car makers fit components to meet certain performance criteria, like stopping distance, fade resistance, and longevity, and it's possible to improve on some aspects by going to other, or better discs and pads.
In the past carmakers have generally held parts for cars up to 10 years old, but that could be changing with the impact of things like the global financial crisis and the high cost of maintaining the inventory. The short answer is that you shouldn’t have to wait for such a part, and you certainly shouldn’t have to wait for what looks like being 16 weeks. That’s simply unacceptable. Go back to Holden Customer Support and demand their action, you could also seek out an air-conditioning specialist who might be able to fix your car faster and more cheaply.
I would suggest it's a problem with the mixture, and I guess it's too lean. Check the oxygen sensors, if they are ok check the system itself.
ASK them to show you where it's rusting. If it's just the coolant that is a rusty colour, have them change the coolant and make sure you regularly change it at least once a year. If the rust is causing a leak, have it repaired.
YOUR first point is valid: always check that the work claimed to have been done actually has been done and getting the old parts is a good way of doing that. At the same time you can check the condition of the parts removed and assure yourself that the work was justified. It can also be a good idea to see what should be done in a service before you take the car in. That way you'll know if something unnecessary has been done or something has been missed when you pick the car up, and there's no better time to sort out problems than before you drive away.
It’s probably the battery. The cold snap we’ve had in recent weeks has been a tough test for batteries, and your battery was probably down a little. That it starts without a problem when warm is further evidence that it’s the battery. Your experience is one we should all take note of, and make a mental note to check the batteries in our cars each year before winter sets in, but we tend to forget about it until we have a problem starting our cars.
It's impossible to predict what might happen in the future, but I would tend to agree with you. I don't see any reason to sell it; it's only six years old and providing you keep it well maintained there's no reason to think it won't continue to give you good service for some years to come.
If your Commodore has IRS you’ve got a tyre-eater on your hands and it would be worth talking to a suspension specialist about fitting a kit to the rear suspension to control the toe-in. Tyre specialists also recommend that you regularly rotate your tyres — 10,000 km is the interval they suggest — and have the alignment checked and reset every 20,000 km. Alignment is often neglected, but is an important contributor to tyre life and can be knocked out simply by hitting a kerb or a pothole. After doing that you could fit a Pirelli or a Michelin tyre, which should give you better tyre life.
