Pros & cons

Pros

  • Genuinely upscale, solidly built cabin with first-rate materials and a quiet, refined ride.
  • Strong, smooth turbocharged V6 that moves the big SUV effortlessly.
  • Standard quattro all-wheel drive plus a usable, if kid-sized, third row.
  • Composed, car-like handling with a plush ride on the optional air suspension.

Cons

  • Premium fuel is recommended and complex electronics are costly to fix out of warranty.
  • Below-average reliability and high running costs, repairs and parts are expensive.
  • Early 2017-2018 build years carry a real 3.0T engine oil-consumption risk.
  • Third row is tight and best left to children, and cargo space behind it is small.

Move your cursor along the line to see the estimated value for any year.

Curve anchored at the entry-trim base MSRP ($49,900). Higher trims started higher (up to $65,400), and options added more.

The curve's data ends 10 years in, so the line levels off after that. Treat the tail as a floor, not a forecast: asking prices for older cars depend mostly on condition, mileage, and the current market, and often sit well above it.
