its not a gcg hiflow.. if it was you would see a GCG Id plate on it. and im pressuming since your asking if its a hiflow there is no badge..
but either way, nice score
try ringing more than your local post office, and dont rely on those noobs when you call the 13**** aust post number
i was waiting for an item that appeard in a post office 3 suburbs away...
why buy a car at a dealership for over 20k and walk away with having to fix lil things everywhere.
and i like how you have diagnosed all the problems with the car without even seeing anything lol.
judging by the leak and worn tyres you can already see that maintaining the car was a low priority.
any dealer will give you that warrantee but they will fix it the cheapest way possible
