The 2 4.2 S3's I had would struggle to get 16mpg. Maybe just about top 20 on a good run very occasionally. One of them was a like new minter, the other was a bit of a shed, but compared to modern big engines, these had a REAL thirst. I have no problem getting 28mpg out of a 6.0 Monaro.

Beautiful looking cars the Series 3 though, and appreciating now too. Still remember the day my old man bought his brand new one home. Silver with red leather that one.
