1987 Mercedes 300D Turbo Diesel with WVO (veggie oil) Conversion

1987 Mercedes 300D turbo diesel with automatic transmission. Converted to run on vegetable oil using a 2-tank Greasecar kit with additional modifications including fuel injector line heaters and adjustable fuel return line. The dual fuel system runs on regular diesel fuel or vegetable oil.
The tires are like new - they hardly have any miles on them. It has a recent alternator, new battery and a new fuel pump. I recently had the fuel injectors out for service and upgraded some fuel system components. The engine starts instantly when you turn the key. The odometer stopped working soon after I bought it at around 165K miles and I estimate it has about 225K miles now. The paint on the top surfaces of the car is oxidized. The windshield has a crack on the passenger side. The A/C does not work.
