Composed, refined ride with strong, efficient 2.0T power and confident quattro all-wheel drive.
Upscale, high-quality cabin with available Virtual Cockpit, Apple CarPlay/Android Auto and intuitive MMI tech.

Cons

Premium-brand maintenance and out-of-warranty dealer repairs are expensive.
Noticeable transmission and stop-start lag off the line in traffic.

Depreciation

2017 entry trim from new typical floor (assumed, past curve data) same model bought new today

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

Curve anchored at the entry-trim base MSRP ($34,900). Higher trims started higher (up to $45,900), 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.
