None would get more than 3 stars as you can't get a higher score without active safety systems. Pretty much all results would be compressed in the 0-2 stars range. Even if a 2003 car would be perfectly safe in a rollover or a offset frontal impact it would be deducted points because it doesn't have lane assists or drive fatigue warning or radar cruise control (barring some S class or 7 series that might have had these features).
