Based on 329 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

If you're standing in front of one, start under the hood: oil leaks dominate, then coolant and engine electronics, and don't skip a scan for active codes. Check the tires next. Hunt a 2018–20 example—that generation holds up best at the same age—while 2012–14 cars are the ones to walk from or negotiate hard. These typically slip below decent around 101,000 miles, so mileage near that mark is your leverage or your exit, not a bargain. Bodywork history is not the main risk.
