Most luxury car enthusiasts have dreamed of owning an Audi car at least once in their life, and nobody who wants a luxury car would be willing to purchase one that breaks the bank through repairs and maintenance. However, that begs the question - are Audi's cars reliable? If so, how much does a reliable Audi cost?

In such a dilemma, the used cars' marketplace comes as a welcome surprise to them, as several reliable Audi models can be found on the used market for accessible prices. These time-tested luxury cars tend not to break the bank and still offer loads of fun, and with a little market research and some much-needed caution, one can find their dream ride.
