Hi There,
I also am an older person, who purchased a similar looking 1996 Bathurst SW20 earlier this year.
Page 3 of this post under the name of FIGO.
I paid $9000, which with 20/20 hind sight & having spent about $2000 getting it to a condition to get it inspected & licensed in W.A. may have been slightly over the odds.
I am not complaining but. It is a great car.
However yours is a couple of years younger & looks even better.
The seller may have a reserve of $10000 or more.
Good Luck !
