Im about to service my audi and would like to avoid going to the Stealers. Are there any reccommended parts i.e. spark plugs, oil filter, etc that people would recommend. Also im coming up to the time where i need to get the Timing (cam) belt changed is this better done at the dealers or should i just go to a good private garage. Its not a company car so its a smack in the pocket at the stealers.
