E63 6-series - V8s a sensible-ish proposition still?

[NiceCupOfTea]

I’ve been perusing the classifieds looking at 630s over the last year or so, fancy a nice one as my next daily. The 3.0 6 seems to be the most sensible route as they are tried and tested (especially pre-facelift). Having had M52 and M54 cars over the last 10 years or so I am fairly well versed with BMW sixes.

However, looking at the way things are going for the keen driver at the moment (especially those unfortunate enough to live within the Greater London area) I am wondering if I should take the risk with a V8. It may be my last chance to own one.

I am aware of valve stem seal issues (look for blue smoke on startup), and I think there is a tricky to reach coolant pipe which I think are the main gotchas - anything else?

Is it likely to be ruinous to run? I am accepting of sub-20s mpg. Tax is presumably an issue on 2006 on cars but is it much worse than in the 630?

645 vs 650?

What say you?

Thanks for the shout. Are they that much more expensive to run over the 6, other than fuel?

Thanks chaps. 635d not an option as I live within ULEZ. The V8 is an urge I feel I need to scratch but I fear it may cost me hugely. As you say, they might be cheap now but they still have expensive car running costs…
