The best car I ever had was my 1975 Range Rover. It was my everyday drive used for work and play I had it between 1985 to 1997 and it just kept going. Yes it was on the 3rd motor and 2 gearbox/transfer case but the rest was original. It had 120,000km (75,000mls)on the clock when I bought her and in the next 12 years I covered around 750,000km (465,000mls) all over Country NSW and Queensland. Only once did it let me down when the thrust shims in the transfer case wore too thin and dropped out, but that was fixed in a few hours when I got her home and off we went again.
A close second was my trusty 1980 Datsun Sunny Wagon, which has only recently been retired. Though no longer doing the outback work I still managed to clock up around 450,000km (280,000mls)in the last 12 years. Far from glamorous, but extremely functional, simple as well as cheap to run and maintain.
