Excited to share my first drive experience in my newly acquired 1984 BMW 735i! The beast is finally back on the road after a two-year restoration project. I'm eager to put it through its paces and see how it handles. Any fellow E23 enthusiasts out there with similar experiences or tips?

I've had my E23 for a few months now and I'm consistently getting around 12mpg in mixed driving. My last tank was on a mix of urban and motorway driving, with a few spirited country roads thrown in. The rest of the owners seem to be averaging mid-teens, and some even higher, so I'm starting to wonder if there's something I can tweak to get better fuel economy out of my 530i.

Hello fellow BMW enthusiasts, I'm considering an engine swap on my E23 and would love to get some input from the community. The original 745i 4-speed automatic has served me well, but I'm intrigued by the prospect of dropping in a high-revving M30B25 six-cylinder from one of the later Euro Bimmers, looking for advice on feasibility, modifications required, and any potential pitfalls to watch out for.

I'm in over my head with this restoration project, folks. My 1978 733i has been sitting idle for years and is a mess - rust, worn-out interior, and a engine that won't turn over. I've got some tools, but no experience. Anyone have advice on where to start?

Hi all, I'm looking to give my 1980s BMW a refresh and wondering if anyone has experience with updating the electronics in an E23. Specifically, I'd like to know about upgrading the stereo system, adding modern navigation and perhaps even getting Bluetooth connectivity working smoothly. Any advice or recommendations would be greatly appreciated!

I've recently taken my '82 732i in for a tune-up and now it's making an unusual rattling noise when idling or driving.

New BMW owner here, just picked up a sweet 1981 733i and can't wait to share my experiences with fellow enthusiasts!
