Depreciation
Move your cursor along the line to see the estimated value for any year.
This listing sits above the typical depreciation curve. Common for heavily-optioned cars and for 2021-2023 model years (pandemic-era pricing); the curve is anchored at base MSRP, which excludes options.
Curve anchored at the entry-trim base MSRP ($33,480). Higher trims started higher (up to $42,945), 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.
