Early (US) 250s are easily identified by the cosmetics. Early have chrome inside rearview mirror, chrome on A pillars and windshield header, chrome ring and horn ring on steering wheel, chrome wipers, chrome gooseneck rearview mirror on the driver's door, hard integrated arm rest, door handle, map pockets on the inside doors (all Euro have this), no side markers on fenders, no front bumper guards. There is a bunch more, but this is easily identifiable.
