BMW 3.0CS, 1974

- Turn on subtitles/CC's if you'd like explanations on what I'm doing throughout the video. - This is a 1974 BMW 3.0CS E9. The original owner parked the car in 1983 with around 70,000 miles on the odometer, after having extensive issues with it since brand new. Since then, the car has mostly been in storage but also kept some what drivable up to now, as it has ran a few years ago but has not been registered for road use since the 1990's. A friend of mine is currently in possession of the car and had some plans to fully restore it, but he instead gave me the opportunity to fix it up to where it can be driven as it is.
