Your right mate, those cars are over priced. But you don't have to have a massive winge about it.
There are some nice cars on here for better prices... You will probably have better luck finding one if you took all of that complaining out of your ad.
For a good condition ADM AE86 with a 4A conversion with little rust and decent paint, expect to pay around $8,000. There are much cheaper cars out there but ones in good condition are getting hard to come by.
Good luck with your search...
