I've owned a 508 GT SW diesel since 2022. Its design is unbeatable for elegance and sporty style, very comfortable for travelling (I'm a sales rep) and has excellent cargo capacity. It's a shame PEUGEOT has discontinued production of this splendid car — it's given me nothing but satisfaction.

On the road it pairs poise with a hint of cheeky agility, rewarding drivers who want refinement without forfeiting a touch of fun — and yes, it still looks great in the driveway.
