Looking To Buy 325i With 100,000 Miles - Anything To Look For?

[BenB]

In the past I've heard many times regarding high mileages on diesels 'Oh that's nothing on a modern diesel' but now I'm looking to perhaps buy a 2007 325i M Sport Touring with almost 100,000 miles on it - will it be likely to be on it's last legs?

I thought the 325i was a less-tuned 3l engine, but the listing says 2495cc. Which is it?
What years had 'efficient dynamics'? The car in question is a 57 plate.

I love the look of the e91,M sort with 18's even more so. On the road today it's still one of my favourite cars to see about, can't believe the shape is a decade old! This would be my first BMW if I buy it. What things should I be wary of?

Thanks!

One more thing- apparently it's got the ABS light on, I've read this could be a sensor, or the pump. Just how costly is the pump if it's that?
I've got an OBDII reader ('Torque' for android and a bluetooth code reader) Will it be easy to determine which is at fault?
Thanks
