Why do most sources list the total production of North American-spec M5s at 1,370 instead of 1,340?
Most sources (including BMW AG itself) list the total production of North American-spec E28 M5s (USA and Canada combined) at 1,370 units. However, this figure does not consider a major flaw in the BMW production database that lists 30 additional VINs which do not, in fact, actually exist. Thus, the accurate figure is 1,340.
