the wheels pictured if in original spec are 2x 16x6 et36 and 2x 16x7 et23.
unsure if they are genuine or repro. are we talking $1100usd or aud? if usd its probly not worth it and am sure if you hunt around you'll find something in oz cheaper, maybe not in as good nick but something you could have polished up for less than you could ship and $ convert them. if in aud then genuine or not i'd buy them. try Mick058 - he may sell you his set of 16x6s/16x8s for reasonable $ if you're hunting.
something for you to read -

a set of 16x6s if genuine and polished typically fetch ~$1500.
