I'll be very french but my choice (T2K choice I mean) will go to two french cars. Either a citroen 2CV or a Peugeot 504 (If unavailable, I would go for the VW Bug). All had great strong points:
Citroën 2CV (deudeuche for those familiar with it):
- It will almost never die on you. In 1990, I found one dating back from 1954 in a dusty storage. It had not run for 15 years. We cleaned the engines and it started (also it couldn't run above 40mph). The fun part is that you still could start it by hand power.
- If it does, you can fix it with minimal tools. However, it is noisy very noisy.
- It can travel with 7 people in it (2 in the front, 3 in the back and 2 siting on the open roof) and still climb a hard slope (I'm sure as I did it, but actually we were 8

).
- You can fit a weapon on the roof
- It will get you through rough terrain almost as well as a jeep
Peugeot 504
- As the deudeuche, it will never die on you.
- It can also be fixed with ease (ask those taxis still running in the middle of Africa)
- It is much bigger than the previous one
- If it's a diesel, it can run on 100% vegetable oil. As it will also run on domestic fuel you will seriously reduce your fuel supply problem (at least in Europe).
Whatever, Make a choice is hard but I would use a pre-1975 car. Even a "Trabant" will do fine. It was tricky but, in the end, it would always start.
