If you look on the major online selling sites (including this one) you’ll find that there are plenty of cars like yours for sale. Prices seem to start around the low to mid-$30,000s with lots of choice in the mid-30s to low-40s range. Prices appear to top out (generally) around the low to mid-50s.

Audi buyers tend to be pretty switched on, so a full service history will make your car more desirable. But prices also vary according to whether the car is a sedan, hatchback or convertible and what options are fitted. Even the colour of a car like this can have a big effect on the asking price.

The best advice is to tap into some of these sites and find an exact match for your car and see what the seller is asking. Don’t forget that dealers will be asking more than private sellers and that what is being asked in the advert is not always what is being paid in reality.

You have been treated appallingly. To have had your car for 15 weeks in the eight months you have owned it since new and not fixed it is an absolute disgrace, and should be a warning to anyone thinking about buying an Audi. The dealer is clearly out of his depth and needs head office help, which doesn’t appear to be coming. You’ve also highlighted the problem with Australia’s consumer laws: they are so weak to be useless. If there were ever a case for a refund or a new car then yours is it. You should have had your money refunded a long time ago, or Audi should have offered you a replacement car. That neither has happened says the company cares little for its customers. That they’re arguing over who is at fault is not your problem, you simply want your car fixed. I understand your concern about taking legal action, but I would urge you have a solicitor write to Audi, with a copy to the dealer, setting out your experience and asking for the company’s help to resolve it.

The WRX is a hottie and great fun, but the S3 is a much classier car. That’s in things like the materials and the way it feels on the road. It gets The Tick from me and I think it’s worth the extra cash.
