The line about Wendy depends on which edit you have - the radio edit has unlocked cars to stop M&S complaining.
It's unlikely 'Freddie' refers to Freddie Mercury, Queen had only formed a year before the song was written, hadn't released their first album, and were probably not contemporaries - certainly not famous enough to be put in a song alongside the established T-Rex (who had kick-started the Glam Rock scene over a year before).
Bowie offered the band Suffragette City - but they didn't like it so he wrote this song specifically for them - it was never written for the Ziggy album.
