Van mileage is becoming increasingly important for setting residual values, according to value experts Glass’s, which claims vans with 40,000-60,000 miles are worth noticeably less than sub-40,000 models, while anything over 100,000 is “difficult to remarket profitably” and 150,000 or above will “only command distress pricing”. Condition has traditionally been more important than mileage in setting van values.
