I had a large yellow 1967 Dodge slant with a big fibro cabin on the back. Getting parts was pretty hard and I think I got the last steering column in Melbourne. Some old guy knew exactly where it was under an immense pile of parts in a back shed.
It was like a tank to handle and I learned how to drive manual in it without being taught. I learned the value of just using side-vision mirrors and knowing exactly what is around me at all times.
It had rust, it had leaks, it had faults and it didn't have much of a 1st gear ...but it was my home for a good period. The seats in the back would fold down into a large double bed with a TV in the top corner. All my gear was stashed under the seats. My rent was just $126 a month in a carpark near Centra Hotel on the Yarra (occassionally inside the big old hangar) while I worked at a Backpacker Hostel where so-called 'shoe-stringers' would pay $17 a night

...mind you, those places were like drunken/stoned orgies.
I paid about $3,000 for the Dodge and found Victoria pretty good towards old cars - unlike NSW which makes up rules to get the old cars off the roads to keep the Car Industry ticking over by forcing people to buy new ones.
Eventually my Dodge broke down on a Bridge in Sydney between St Clair and St Marys. A modern 4x4 Landcruiser had to tow me down to the servo

and eventually I got it towed back to my oldies where it sat for ages until I sold it to some enthusiast for just $100.
...none, the less - I loved the experience of living in it. Nothing like just driving off and opening the back doors to an endless backyard of fields.
