Usually on higher mileage cars as well. It leaks between where the transmission mounts to the engine. This is not an e46 but is what it looks like when a rear main seal leaks.

This kind of picture not necessarily means rear main seal, it might be a leaking oil pan gasket too. Ask me how I know. Leaking rear main seal is pretty rare on M54s. Thus, if you see oil drops at the back of the engine - do not panic, it most likely an oil pan gasket and not rear main seal.
