It is possible to find some with the claimed low mileage. I know my 240D is correct at 138k but only because it is a family car and I know its history. My 280E is another story. It reads 88k but the odometer has stopped working as it has gotten warmer outside so its true mileage is unknown and frankly is irrelevant for this car since if I ever sell it then it will most likely be for parts. Documentation is key for all old cars but even more so for these with known issues in the odometer.
