Audi’s lease horribly because compared to other brands they offer fewer incentives and generally less discounts. Comparing them to similar cars from Alfa Romeo or Infiniti they can often be gotten with 20% off, you’ll almost never get anywhere near that, even for sedans which Audi are more flexible with pricing.
You’ll need to put in far more work to get a good deal on an Audi (assuming you don’t work with a broker), and even then it will look poor in comparison to similar vehicles from other manufacturers.
Have a look at the Trophy thread and compare the Audi deals to BMW, Merc, etc: Trophy Garage [ Photos ]. The difference is often 33% or more for extreme deals. I’ve owned a Golf R and Audi TT, my wife has a Q5 so we’re not anti-Audi, but they just don’t often offer much value.
