I would buy a d9 406 instead, same engine, much better shape to the boot, its a proper estate not an sw, the 407 tailgate opening is really poor for the cars size, or get a citroen c5 with the same engine.
if the dpf causes issue just get it removed and mapped out, you can also gain a decent 30-40 bhp on a standard engine.
in any case listen out for dmf noises, ticking injectors, boost leaks, excessive snoke and lack of power, nothing too difficult to fix but can add up in cost especially if you dont fix it yourself.
very similar in operation to the dw10ated4, but a longer stroke bigger bore taller engine.
