Just picked her up last Wednesday as a "winter beater". She's got 177,xxx on the clock, but a newly rebuilt-transmission. I also fixed the SOS Error with an optical loop and a Dremel. I immediately took her on a 300 mile road trip and had exactly zero problems. Very happy so far. I've had a couple Bimmers previously - both 3-series (an E46 and an F30). Looking forward to learning more about my E61 now.

 

That's a pretty classy "beater" you have there! to the forum!
