1.2 pure tech engine have other problems other than wetbelt?

Got a 22plate corsa with 1.2 puretech turbo engine, and tbh I enjoy it for the we pay its a great little city car thats given us no problems yet. We are on pcp and in 6 months have got to decide what we are going to do we are unlikely to upgrade to new corsa as the cost jump is criminal and features are the same if not more striped back.

Im in two minds on if to buy out our pcp or look elsewhere for a car,We are a low mileage household (5k a year). My concern which i learnt from the Internet is concern over the engine long term. I know wet belts are not great but are there any other issues to know about ?

We service at our local dealership every year and have seen a wet belt change price is about £600 which although im not happy it has to be done every 5/6 years i would accept it as fairly reasonable on going cost aslong ad the rest of the engine reliability is bullet proof.

Cars on 14k miles fully serviced and hoping with a belt change every 6 years it will just last and last
