1982 Mercedes-Benz S-Class 300SD 3.0 turbo diesel from North America
Drive for free - forever
Automatic transmission rebuilt at 210,000.
Turbo is a bit noisy at highway speeds, but the car is extremely comfortable, and handles like a sports car on windy mountain roads.
It has been modified with a vegetable fuel system from greasecar.com, enabling 90% plus of driving on free waste cooking oil widely available from restaurants, so operating costs are negligible.
The diesel engine never needs service or tune-ups, and it is exempt from SMOG regulations.
Would you buy another car from this manufacturer? Yes
