W222 Reliability

[TG105]

I’m looking at a 12-18month old W222 350.

I do around 18-20k miles p.a., so not huge. Obviously the MB S Class is an incredible car, however I’m just wondering what are the pitfalls of owning something of that complexity if it goes wrong? I’ve heard horror stories costing over £10k. Would (could) you extend the warranty?

Edit: an idea of running costs too would be really handy.

The “sensible” choice is a 530d but there’s something about the S-class I can’t turn down!

Thanks
