Yeah I have no life lol...
Honestly, I'd be looking privately on these forums... If you want to go with a dealer, I understand, but be aware that you are immediately overcapitalising... (IE it will lose LOTS of value the minute you buy it...) Better off letting someone else take that hit in my opinion...
I sold my series 1 sedan (auto) with heaps of mods for 15K only a few weeks ago... I know of another friend who sold his series 1.5 coupe (auto) reasonably stock for 15K around the same time... Smoothline sold his series 1 (manual) with plenty of mods for somewhere around 16K just recently... There are also plenty of others for sale interstate... If you buy from here, you're generally buying from an enthusiast, not someone trying to make a living...
If you have to buy from a dealer, then just keep on looking till you find the car that you want and be aware that the dealer DOES have room to move on the price... Keep reading these forums and learn the things that you should be looking at before you buy... There is heaps of info here...
