2001 BMW E39 M5 review – why this might be my favourite car EVER

I won't lie – I've had a soft spot for the E39 M5 for a very long time. Now I've finally got my hands on one, so join me as I find out whether it's actually as good as I thought. It's a big old naturally aspirated 4.9-litre V8 thug of a saloon car – but how does it feel 20 years after it was built?
