Even so, to clear up something for everyone.
Roadworthy does not depend on modifications done. There are certain guidlines that they must follow. Other than that, as long as the car is essentially safe, it should pass.
If you have a blue plate for your mods, then they should not even need to be checked in a roadworthy
Silly things pass like:
You can have absolutely no baffling left in your rear muffler but if it doesn't exceed noise limits and there are no holes then it passes.
No spare needs to be present.
Only driver's side window has to work
Oil leaks are ok as long as (after cleaned) they do not form one drip within 10 minutes.
Surface rust is ok but can't poke anything through it.
As you can see it's not like you have to have a new car to pass.
