BMW X3 Depreciation & Resale Value

The 2017 X3 is the value sweet spot: it sits just past the model's steepest one-year depreciation drop, so the first owner has already absorbed the biggest loss. Expect to pay around $12,950 for a typical example, and the M40i trim will hold its value best from there. As always, a well-maintained, accident-free example with average mileage for its age is worth paying a little more for than a cheap car with a questionable history. Whatever year you settle on, budget for a pre-purchase inspection — at a couple hundred dollars, it's the cheapest insurance against an expensive surprise down the road.

The M40i retains the most value, depreciating about 57.0% on average across model years in our data. Trim choice can swing resale by thousands of dollars over a few years, because desirable trims stay in demand on the used market while stripped-down or niche trims sell at a discount. It's also worth comparing the trim premium new versus used — a pricier trim sometimes depreciates enough to become the smarter used buy. If you expect to resell, the M40i is the safer bet; if you're keeping the car long-term, buy the trim with the features you actually want and worry less about resale.

Yes. In our data, gas X3s depreciate about 66.8% on average, versus roughly 77.2% for diesel versions. Powertrain affects resale through fuel costs, buyer demand, and perceived long-term reliability. If lower depreciation matters most, lean toward the gas version — but factor in fuel savings and your annual mileage, which can outweigh a few points of depreciation either way. Run the math for your own driving before deciding: the cheapest car to own over your ownership period isn't always the one that depreciates least on paper.
