X308 - what to look out for?

[TopGear7]

Hi,

I've been keeping a look out for a X300 3.2 for a while now and I'm aware of the issues to look out for. The general consensus appears to be the engine is pretty bullet proof.

However I've just come across this X308:

and it looks like truly incredible value for money. Could anyone give me some tips to what to look out for? I've heard these are not as reliable as the X308 but as long there aren't any potential ridiculous bills looming for these and I'm not too concerned.

Thanks
