Based on 343 used BMWs we inspected, they tend to be in noticeably better shape than the typical used car we inspect — average condition 67/100 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 ~184k. Shopping a BMW near that mileage? Expect more wear ahead — see which makes give the best odds at your budget.

Share of BMWs in good shape (scoring 60+/100) by mileage and by age when we inspected them (each dot ≥5 cars; a band under 20 cars follows the nearby bands, so a run above the all-cars line stays above it, and a band of 20 or more uses the rate we measured; where a band has too few cars, the line follows the trend between the bands on either side; rolled-back odometers excluded from the mileage curve). The dashed grey curve is all cars we check.

2017 BMW 430i · 114k mi — flagged: low coolant / cooling system issues, oil leaks, dirty or low engine oil. Inspected Nov 8.
2017 BMW 740I · 108k mi — flagged: oil leaks, battery condition, fault codes recently cleared. Inspected Oct 24.
The bottom line

Start under the hood. Oil leaks show up on more than half of these cars and cooling problems travel with them, so a dry driveway and a full reservoir matter more than a shiny nose. Then scan for active codes — they are common, and cleared history is common enough that a dark dash is not a clean bill. Age-adjusted shape climbs from the 2012–14 cars to the 2018–20 group, which is the smarter window if a scan is actually clean. The typical car slips below decent around 101,000 miles, near the back of the brand rankings. Past that, leaks plus codes, worn tires, or leaking shocks justify a hard discount or a walk.
