Based on 333 used BMWs we inspected, they tend to be in noticeably better shape than the typical used car we inspect — average condition 66/100 vs 61 for all cars we check. Every number on this page comes from real pre-purchase inspections — cars people were about to buy and paid an independent inspector to go through point by point, engine to underbody, paint depth to error codes. Not owner surveys, not warranty statistics, not forum lore: what we actually found.

How long does a BMW last?

Across every BMW body style we've inspected — sedans, SUVs and anything else pooled together — the average one's condition dips below decent (a 55/100 score) around ~101k miles. It ranks BMW #20 of 24 brands we have enough data to rate; the longest-lasting, Tesla, holds up to ~197k. Shopping a BMW near that mileage? Expect more wear ahead — see which makes give the best odds at your budget.

The bottom line

BMW used cars live or die by the engine bay. Oil leaks show up on more than half of them, with live error codes and cooling trouble close behind, so pop the hood and scan for codes before you even talk money. Skip the 2012–14 cars if you can and hunt the 2018–20 generation instead. Treat 101,000 miles as the typical drop-off, knock the price if you see a leak, and walk when leaks and cooling issues stack on the same car.
