how much is that doggy on the driveway... the one with the waggaly tail...

[dickies12]

hello all, i'm off to buy my first s12 on sunday
but i dont know how much to give

it's white on an f plate, 107k, few surface rust
patches on the pannels and has a blowing manifold
gasket.

any ideas on what would be fair ??????

also is there anything terminally bad i should check for???
i really don't need another nail on the drive

cheers all
