Based on 310 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 ~100k miles. It ranks BMW #20 of 24 brands we have enough data to rate; the longest-lasting, Tesla, holds up to ~185k. Shopping a BMW near that mileage? Expect more wear ahead — see which makes give the best odds at your budget.

The bottom line

Engine trouble defines the used BMW experience more than bodywork ever will. Oil leaks alone turn up on 56 percent of cars, frequently joined by coolant problems and active error codes, so start every inspection under the hood and with a full scan rather than admiring the paint. Longevity is a soft spot—these cars typically slip below decent condition around 100,000 miles and rank near the bottom of the pack—so treat higher-mileage examples as negotiation fodder or walk-aways. The 2018-and-newer generation is the clear sweet spot, holding good shape far more often once age is factored in; older ones demand sharper pricing and zero tolerance for ignored leaks.
