Great car with a smooth ride. I have 308 SW GT, with the 180HP PHEV engine

150,000 km in 2 years — SW BlueHDi 1.5L 30cv. Comfortable, excellent gearbox. Maybe a bit noisy on the motorway, with air noise around the front doors. A slightly punchier engine would be welcome. The entire timing system was replaced under warranty at 110,000 km.
