Hello to all from down under. Hope all are well in these interesting times. I'm new to the wonderful world of BMW's. I've always owned V8 Fords or Toyota 4wd's. As a qualified automotive mechanic for nearly 26 years I've always owned what I knew best. It's not that I haven't admired BMW's just never owned one until now, for some odd reason they don't hold their value here in Australia......... This series 3 I bought from a car yard is such a beautiful car to drive. I've fixed the common faults with them (valve guides and full timing chain set) and 1 window regulator. I thought I'd join this forum to glean what I can. The factory stereo Bluetooth doesn't work anymore so I was wondering what direction to go there. I'm 46 with a family so a loud doof doof sound system wont really be needed. just something the phone will go through again. Factory or aftermarket? Also the exhaust looks odd to me. This is the 2ltr petrol non turbo. It looks like extractors up front with twin Catalytic converters, then it's twin exhaust until about half way down the car then joins into a weird single system with a rear muffler shaped like a pillow? I'm tempted to start again from the flange after the cats and make it look nice, neat and better flowing than what's there. Thoughts?
