The Self Proclaimed “[Mercedes Benz 1000 SEC]”Spotted Near Heathrow London

Spotted this on the back of a trailer near Heathrow yesterday.

Cool looking Mercedes with a wide arch kit, finished in white with gold alloys. It looked like it had driven straight out of Miami Vice.

What caught my eye was the "1000 SEC" badging on the boot. I've seen plenty of AMG, Brabus, Lorinser and Koenig conversions over the years, but I've never come across one wearing this badge before.

Is the 1000 SEC linked to a period tuner, or is it simply something an owner has added? I'd be interested to know the story behind it
