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 ($18,995). Higher trims started higher (up to $25,995), 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.
Cost to own
| Repairs (rises with mileage) | ≈ $450–500/yr |
| Insurance (medium tier) | ≈ $1,900–2,000/yr |
| Expected lifespan | ~200k miles |
National-average estimates based on public data. Your costs vary by region, driver, and condition.
