Peugeot 508 SW

The Peugeot 508 SW dresses up as a sleek estate, blending Parisian flair with usable loadspace so you don't have to choose between style and weekend practicality. Inside it's a driver-focused cabin with quality materials and clever packaging that makes it a sensible, slightly mischievous choice for buyers who want an executive feel without the buttoned-up seriousness.

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.
