Depreciation

2018 entry trim from new typical floor (assumed, past curve data)

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

Curve anchored at the entry-trim base MSRP ($33,400). Higher trims started higher (up to $50,600), 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.
