XF 2.7 and 3.0 diesel reliability

[Sir Fergie]

My brother MAY possibly be changing his car this year.

He likes the look of the XF - especially the interiors - and is considering a 2.7 - however a 3.0 may work out better due to the cheaper road tax*.

So im wondering if the good people of this forum could give me the lowdown on just how good - or bad reliability of these are.

Have read tales of woe on the 2.7 both here and elsewhere - but what im wondering is - are these tales of woe - isolated incidents - or are they indicative of widespread reliability issues.

Hes well aware that Jags don't always have the best reputation - so be all means be brutally honest

Thanks guys
