BMW 7 Series FAQs

Check out real-world situations relating to the BMW 7 Series here, particularly what our experts have to say about them.

• Gassing up a bmw

  FEW 7 Series BMW have been converted to LPG, so there's little experience in the industry. It could be an expensive conversion and probably not worth doing.

• At home on the grange

  THE HSV and the BMW are quite different cars, which makes it hard to compare them realistically. The BMW has lots of badge cred and is a good car in all respects. The HSV has limited badge appeal and isn't as good a car. That said, the HSV will cost less, be less expensive to service and Holden parts are far less expensive than BMW parts.

• What should I know before buying a 2004 BMW 7 Series?

  Some of these older luxury cars are tremendous bargains. Or, at least, they look like it in the classified adverts. There are a couple of reasons they're so cheap second-hand. The first is that people are (often rightly) scared of them going bang in an expensive way and requiring lots of pricey repairs. The second is called the funnel effect and happens when a luxury car like the 7-Series is bought brand-new usually by corporate customers. But, when the car is ready to be traded in a few years later, there simply isn't the volume of private buyers waiting for one to hit the market. So prices plummet. The same thing happens to Mercedes-Benzes, Audis and other luxury brands, too; it's not just a BMW thing.

  Meantime, the rules of engagement are the same for any used car. The most important thing is not the distance the car has covered, but how well it's been maintained over the years. You need to see a stamped, up-to-date service handbook with no glaring gaps in the service history. Without that document, you could be buying an abused car that will let you down and empty your wallet.

  The other thing to be a bit wary of in a 7-Series BMW of this vintage is the ex-hotel courtesy car. Back in the day, BMW had plenty of 7-Series to shift and a relative lack of takers, so the company offered them to hire-car and limousine taxi operators for about the same (leased) cost as a Holden Caprice. That's how so many of them wound up wearing a groove from the city to the airport.

  A good, well maintained ex-hire car should be okay, but bear in mind a lot of them led pretty hard lives. That included a variety of drivers who may or may not have cared very much and long hours idling in gridlock traffic. Check the condition of the backseat to see whether it's been used often (does the wear in the back match that in the front?) and check the area around the rear bumper. This was often damaged as a million suitcases were loaded and unloaded from the boot.
