I'm sorry to say you may not like what you hear (at least from me).....a V6 car is going to drag the price down....its LHD which limits your market as it will be 2 years till most states allow it to be registered LHD (30 years old)...I think WA its 15 years.
But I suppose if theres two years till it can be registered, thats enough time to paint it and trim it etc....but thats a fair bit of money to invest in a not particularly desireable model.
If you've got import paperwork (you must be able to prove it was an authorised import or you'll never get it registered), then it might be worth $3-4K? Its really hard to say, 3rd gens are all over the place, and not selling real well at the moment.
This is of course, just my humble opinion....and everyone's got an opinion. A car like this is pretty hard to pin down on a price.
