The rules change every 2 weeks, thats why.
I went to get my rego check done and the guy was like "we cant do import, new rules brought in recently". I told him to give the RTA a call, and they told him "oh yeah now you can do them, new rules brought in recently".
Theres no consistency. The only thing that remains consistant is if you end up getting it passed at an inspection station, you're surely gonna get a letter to say you've gotta go past dickson anyways.
