530d vs 730d running costs?

[RicoOS]

I've already asked about a potential purchase of an F11 530d touring and thanks for the very useful response to everyone who answered. But as a secondary question, what are the likely maintenance cost differences between an F11 530d touring and a F01 730d?

Would be done by a specialist and would be doing the same likely miles so circa 20-25kpa, both starting circa 2010 plate and probably already with 100k on the clock, with full history.

Part of me has a hankering for that super luxury and I'm just trying to understand the likely maintenance cost difference, given the same engine etc?

If you can try and stretch for a facelift F01 - 8 speed gearbox, stop and start, and air suspension as standard. It consumes less and pulls better then the pre facelift model. Sports model looks quite nice and not as ubiquitous as F10/11s I would say there isn't much difference vs F11 weight wise but happily stand corrected. Maintenance pretty much the same. Tyres are one size bigger than those on the 5 series.
