2006 Mercedes-Benz M-Class

I have a 06 Mercedes ML 500 with 240k miles ..that I drive daily. The car does have a couple issues. It has a parasitic drain meaning if you let it sit longer than 48 hours it kills the battery so you have to be mechanically inclined to figure out what is causing the battery drainage. I normally just unhook the negative side of the battery post at night .. started after I installed a brand new battery ..It also will need coils and spark plugs a tuneup. I’ve just put so many new parts into the truck. It is currently inspected and I do have a clean title in hand so if you’re serious, please text me at nine 8 four two 9 eight five nine zero nine I’m sure this truck has plenty more. Life in it cold ac / good heat
