I am looking to replace my F30 320d auto, looking at either a 428i/430d or a 530d/535d. Trade in value of around £9.5k. Ideally, I wouldn't want to spend more than an extra £9.5k, which works out at around £210/month over 48 months, hoping the residual value will be around the extra amount I've put in.
Must have options are a pro sat nav (makes the interior), upgraded speakers (can't stand the standard audio in my 3), Xenon/LED headlights (won't be a problem in this range), EURO 6 engine if diesel, and at least sports seats or better for comfort. I will be doing ~14k miles a year, most of it on A roads, with some heavy traffic thrown in.
My fairly local dealership has this on offer. My concern is the relatively high mileage, as I would be hitting 100k at the end of ownership, and the potential low residuals (old model).

Would it be worth making an offer on this around the £18k mark, or should I start looking for something more reasonable instead?
Alternatively, I've been looking at an Audi A4 B9 with the Tech Pack. It feels a lot more modern inside, but certain quality aspects are lacking in comparison to the BMW, and I wouldn't be able to get the better engine with it.
