I want to know if the batteries for the 520s are really located in the engine compartment unlike most e34s wherein their batteries are located inside the car either under the front seat or at the rear seat. I have an m50 engine, 92 model. I wanna make sure if this is the right setting for my car or if i need to place it where it is rightfully is...

Can anyone who owns a 520i or anyone knowledgeable confirm this?

TIA.
