Everything wears out no matter how well maintained and if not the engine then certainly the autobox and every other bit of that car that goes round and round or up and down is well past any design life.If you bought it a week earlier for £12k? Yeah not so easy to be sanguine. Super leggy cars need to be really, really cheap if you're sensible but stuff like this always just goes to someone who is busting for a new plate on their 5 series but really can't afford a couple of grand more for one with a quarter of the miles.I agree, it s a lot of money to sink into a massive risk.I seem to recall BMW state that these ZF8 transmissions are sealed for life and require no oil changes. It would be interesting to see if this has done 300,000 miles on the same transmission oil, whether it s had any servicing or even replacement in that time. It s hard to imagine it would have just run happily for all those miles on the factory oil.Surely it would just be brown, stinking water by that point...Years ago, we had a series of Peugeot 206s - with the awful AL4 auto gearbox. Peugeot used to claim they were sealed for life - from the documentation it seemed more like "sealed for the life of the warranty". The manufacturers of the box itself recommended a fluid level check every 20k miles and replacement at 60k, which was more like it.Even when they weren't faulty, those gearboxes were bloody awful. We never had any major issues with the 206s themselves, most got close to 200k but the gearboxes were what killed them.Iveco specialist supply service kits for the ZF8.A friend got to 270k in his, running at 7 tonne most of the time with a trailer, before it let go.now he is running a two car 7.2 tonne.
