Mercedes C Class Estate

The Mercedes C-Class wagon dresses Mercedes refinement in a sensible, practical package, marrying a sleek estate silhouette with a plush, high-quality cabin that feels more premium than its badge implies. It quietly soaks up motorway miles and cartloads of family kit with composed handling and effortless comfort — a clever alternative to an SUV for buyers who still like to steer.

To me, the CLA's interior and front end are tasteless and an affront — the C estate is clearly much more attractive.
