the scene in newcastle wasn't to bad, I know becuase I lived there for seven years, parts were very easy to get when I was living at mayfeild, belmont and toronto (usually walking distance but when I lived at wallsend.there was usually a extra 10 minutes drive.
there are frequent runs and cruises in the area to keep you busy and meet other car people.
on a Sunday the nobbys beach area becomes a "strictly cruzing" area with every man and his dog out cruising in all styles of cars.
by the way I spent the 7 years I lived there driving a FC holden and couldnt think of a better car to do it in.
a runner on the road starts at about $3500
a good one is about $6000 and a smick one is around $10000 + and if you look after it you should get your money back.
look for rust in the subframe ( under the front of the car) and in the bottom front corners of the floor, also check the rails under the car but dont stress about them to much as they are easily repairable if you have a welder.
