Pros & cons

Pros

  • Strong used value, with the sorted 2016-2018 35i among the best X5 buys.

Cons

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

Curve anchored at the entry-trim base MSRP ($57,200). Higher trims started higher (up to $74,050), 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.
