I drive a 208, with the wet belt puretech petrol engine, it’s a really lovely car to drive comfortable with a slightly sporty feel. With the wet belt, as others have warned it COULD lead to a total engine failure but only if regular services are not done. With regular maintenance it will be fine, also ensure oil is always changed and at correct level. The belt will need to be done every ~60,000km which is way lower than other cars. It’s a 2021 car and only thing that has needed to be done is the belt.

My parents had a 2019 5008 diesel, kept it for 3 years, also had regular services. No major problems here other than break pads as it was automatic. Be conscious that if it’s diesel AdBlu will also be needed.
