The authority had to consider whether a Facebook post could constitute an advertisement and found that it could because the page had been created to promote the company.
The authority ordered Platinum Wheels to remove the post and today it appeared to have been taken down.
Platinum Wheels manager Nick Hoyle said they had not intended to cause offence by posting the image.
"I understand why there was a complaint laid and I can totally see why they've taken the action they have. No worries at all.
"From our end, we try to have a bit of fun with our Facebook, we're always posted things that are likely to get a reaction out of people and some people lap it up. So what do you do? If you're always trying to be PC for everyone out there then you're sort of letting society rule how you live your life."
He said he was sorry to anyone who took offence.
"We're not out there to make fun of people or categorise people or anything like that. When it comes down to it, we just saw it as an opportunity to have a bit of a laugh about the Ford-Holden relationship. Some people got upset about it and we're sorry about that. But for the handful of people that complained, 1600 out there thought it was hilarious and shared it."
He disputed that it was an advertisement at all.
