The 1994 BMW 840 fails its MOT first time in only 71.5% of cases, sitting well below the UK average of 80%—a red flag for reliability. Worse, one in four of these cars (24%) has recorded a dangerous defect at some point, which is a serious concern for a potential buyer weighing safety risk.

These 840s are averaging nearly 116,000 miles, which is reasonable for a 30-year-old car, but the real worry lies in the high failure count: 3.79 failures per vehicle suggests persistent mechanical problems across the fleet. With nearly 19 advisories per test, these are cars that demand constant attention and money—budget for a full pre-purchase inspection by a BMW specialist and walk away if the service history is patchy or incomplete.
