Hi there, I have just read your post.
I am selling a running '85 AB GSR Cordia at the moment. It is in good condition. I have just replaced the timing / balance shaft belts. I am looking to sell for more that what you are looking for so this car may not be suitable for you. However buying a car for $500 dollars will not get you a lot and you may end up spending a fair bit of money getting it running and back on the road. Therefore it could be worth considering paying a bit more at the start, not having to spend a lot of money and be driving a car a lot sooner. Message me at
bitilley@hotmail.com if you have any questions. I have posted some photos on another thread however can send you more directly if you wish. The car is located in Craigieburn.
Regards
Ben
