I have a 1971 E9 that I love to drive but it is temperamental. But when it runs I always get a lot of thumbs up or big smiles when my car is spotted. The latest quirk is when I turn off the headlights the running lights stay on. I think I need a new switch, will take it to my mechanic this next week to sort it out. Hope finding a new switch isn't a problem. It also leaks oil, but I say it's just marking its turf. Overall I love the car, its engine seems strong and I continue to repair and fix things as I go along. Windows are a challenge. Trying to keep it as stock as I can. Anyhow here's where I am at this point (photographs well but does need a paint job or touch up at least).
