Well I once had this really hot indian curry...........
Just kidding..
I know a tow truck driver who calls me from time to time and pays me to recover vehicles which he can't to. I recovered a Hilux with a couple of P platers from Bathurst from the same spot you're talking about (down near the Beach at Menai). Just so you know, you're NOT supposed to be in this area unless you're on an official clean up day. Anyway back to the story. This guy was in so far that his passenger seat was pretty much under water. There was around 1 foot deep water inside the cabin and he'd been sitting there since 10am (I got there around 5.30pm).
Down to the recovery side of things. I tried snatching him a few times with no luck, tried winching but kept dragging myself towards him rather than him out of the bog hole. Ended up chaining my rear bar to a tree and winching him out. Once I was all chained up it wasn't much stress to winch him out.
Once he's out he goes to start his engine and I tell him it's probably a good idea to check the engine for water first. Pulls out the dip stick and the entire tube is filled with water. Ended up having to tow him out to Heathcoat road where the towie put him on the back of his truck and away to have an engine replacement.
I've got a few more (including a TJ driver smoking a clutch in a 2 week old Jeep), but that one is probably the best.
