I knew of someone selling a cheap E39 and was temped myself, but can't have more than one car at a time so sorted it for my boss to buy it.
I filled it up today(£97.62 ) and what a thing to drive! Its so smooth and quiet and just feels so solid. This ones done loads of miles(207,000) and it still feels good.
Needless to say I am jealous and looking at the 320d with distaste at the moment
The MAF is fooked so the throttle doesn't do much at the moment, but you really don't try to drive fast in it anyway!
