What is the most reliable engine type for the Ford Mondeo?

I am considering buying a Ford Mondeo, but I'm not sure which engine type is the most reliable. Can you give me some advice on which engine type to choose and why?

I highly recommend the 2.0L EcoBoost engine for the Ford Mondeo. It offers a good balance of power and fuel efficiency.

Personally, I would go for the 1.5L EcoBoost engine. It may have slightly less power, but it's more fuel efficient and has proven to be reliable in my experience.
