Based on 339 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 ~182k. 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.

The bottom line

Most of these cars have had a panel repainted, so a clean flank is not proof the history is clean. What should decide the buy is the engine and the electronics: oil leaks show up on 54% of them, cooling trouble and active or cleared codes are common too, and condition tends to slip below decent around 101,000 miles, near the bottom of the brand rankings. Shop a 2018–20 first. On a 2012–14, leaks, low coolant, worn tires, or cleared codes are reasons to cut the price hard or walk away.
