2005 S500 No Crank No Start After Sitting

I’m considering buying a 2005 S500 with about 140k miles. The car had been sitting for about 9 months without being started. Obviously the battery was dead so the owner jumped it and it started, but once he shut the car off it would not restart. I decided to drop a battery in it to see if it would start with that, but it did not crank or start. All other systems worked fine and my (basic) scanner did not pick up any codes that would cause a check engine light or make the car unable to run. We tried to push the car out of the street spot it was in to get it towed, but the car would not shift from park. Could anyone tell me what the issue might be and if it would be worth it to buy?
Thanks in advance

watch the video I posted it shows you where the fuses are located in the box under the passenger floor . You can’t get these fuses at an auto parts store you’ll need to get them from a junk car or speciality stereo store



once you get it started , that’s just the beginning . how do we know what other problems it has ? Have to get it running first to see what else maybe wrong . I’m sure that isn’t the only problem with the car . So your question is ridiculous .
If you think An obd2 code scanner is capable of diagnosing a nonrunning Mercedes you shouldn’t be buying any Mercedes . It’s useless for diagnosing a Mercedes . it only helps with emissions related codes .
At a minimum you need a foxwell nt510 with the Mercedes software or a true star Diagnosis system (the factory repair computer system )

they have a Reed valve which clogs and lets water enter the passenger compartment, short circuiting the SAM
