6000 SUX in Robocop

Hey mates. I just watched Robocop again (the original one) and started to look for some memes in it. Like “I’d buy that for a dollar” catch phrase.

Also I noticed the car called “6000 SUX” in it. I searched a bit but couldn’t find much intel about it.

So is it simply a pun ? You know SUX = SUCKS, about the failed utomobile industry in Detroit ? Or am I missing something ?
