This has been a real mixture of love and hate... but right now (because I FINALLY got it running), it's love
Picked this 1984 BMW e28 almost a year ago from an older couple in south MN - 58k on the clock but a non runner and had been sat in a garage for 10-15yrs.
It's taken a lot of work (new gas tanks for 40yr cars aren't cheap) and help from the e28 forum to get it running, but after a brake job and decent wheels and tires, I was finally able to get it out on the road 2 weeks ago.
It's now with a mechanic in Chicago, who's going through some things I'm not able to, but in a month or so, it should be mechanically sound and ready for a new stereo and (a little) rust repair.
