Out of warranty Interesting car costs

[SixCylinders]

Morning PH

looking at swapping to one of the following cars after Christmas:

Ghibli 2015 ish 3.0 petrol with 70k miles
B8.5 S4 50k ish miles top spec
B9 S4 70-80k miles 2017 ish
XE V6 S 2016 60k ish miles

Im not too fussy about higher running costs but are these cars in the same league when it comes to parts and servicing prices? My hearts set on the Maserati and all of them would be serviced at either a specialist or independent (I know their dealers are a joke for servicing and you wouldn't do that on a 15k car) But am I a lot more likely to get bitten going for the Ghibli?

TIA

A friend had a Ghibli... lovely and special car but I do recall parts prices were quite toppy.

The XF S is the pick out of those followed by the Ghibli.

The Maserati is a bit pricey parts wise but a good specialist will keep the labour sensible.
