G'day mate,
I came over 7 years ago and bought a 3dr and a RS500 with me and had no problem selling either for about double what they were fetching in UK at the time.
But my mate bought his Mallard escort out and hasn't had any reasonable offers on it, He has been here 8yrs and still has it.
They normally get advertised at $60k but have heard of them going for $45k ish
Not many people know what they are doing with them here so if you can't maintain it and work on it then I wouldn't bother.
Gold coast is nice I live in Tasmania now but still have a place in Labrador CBD. Loads of people from Uk car scene are now over here.
Good luck with your move.
Regards
Mark
