However, the perceived quality of the switchgear, a few of the plastics, and a slightly unintuitive dash layout doesn't quite live up to the standards of the minimalist interiors that generally sets the German offerings apart.
There's plenty of room in the back and the boot is a good shape, though, even if rear legroom and boot capacity falls short of what you'd get in plenty of rivals, including the Skoda Superb estate and Subaru Outback.
On the equipment front, Peugeot has kept it simple with only one trim level to choose from - RXH, which equips the car with 18in alloy wheels, a panoramic glass roof, satin roof rails and a rugged bodykit, alongside technology such as parking sensors, heated door mirrors, electric windows, adaptive LED headlights, and keyless start and entry. Inside there is cruise control, dual-zone climate control, leather upholstery, electrically adjustable and heated front seats, head-up display and Peugeot's 7.0in touchscreen infotainment system complete with DAB radio, reversing camera, sat nav, Bluetooth and USB connectivity.
The way the diesel RXH drives is more of a letdown. It's absolutely fine in normal use, but it's no more than fine. Its auto 'box is pretty sluggish, and even under moderate acceleration or on an incline, it sometimes decides to change down when you don't expect it to.
The engine stop-start system is similarly unintuitive, as it's quite slow to fire up the engine and can make quick getaways jerky and unpredictable. Throw in some damp roads and you can add a liberal dose of wheelspin for a really scrappy start, too.
Still, once you're underway, the gearbox is smooth enough most of the time and keeps the engine in its torquey comfort zone.
The steering feels quite artificial and doesn't offer much joy if you want to tackle your favourite country road, but it's well-weighted and predictable, so adds to the easy-going character and makes it easy to pilot the 508 precisely.
You're probably not going to be too bothered about that country road anyway since the 508 RXH is not the keenest through corners. Body roll is actually quite progressive and not too intrusive, so you don't get the exaggerated wallow and pitch of some soft, jacked-up estates.
There's little communication through the controls, however, and the understeer-oriented chassis ensures that any potentially spirited drives will be quite underwhelming.
For all that, ride comfort and refinement could be better, too. It's settled on the motorway, which is truthfully where the 508 feels most at home anyway, but high-frequency undulations have the suspension working hard, and the whole car shudders over mid-corner bumps. Road and wind noise are noticeable at higher speeds, too.
This is one of those cars that, when someone asks you what it's like, you nod and say "nice". It's relaxing to drive, the interior looks good and is comfortable and spacious and you've got all the kit you could want.
It's also worth looking at as a company car thanks to its impressive emissions, provided you're just after a top-spec estate and not something with off-road or heavy utilitarian potential.
After all, the 508 RXH has a fairly low maximum towing capacity of 1475kg and will be about as useful as a tissue-paper umbrella in a monsoon when it comes to any really uncivilised terrain.
