hi, a few days ago i was in my neighbours garage, and i guess what i founbd in there? a 1977 bmw 520. no one had driven the car in 4 years. my neighbour said she got a new car because this one was too big for her. its got automatic trans and a/c. she told me that if i want it, i can take it off her hands for free. obviously the cars battery is dead, please advise me what i can do with the battery, and how much do u think that id have to invest to get the car running again?
