The UK’s used car market continues to grow, with purchases rising 6.5% in Q1 2024 alone. In this fast-moving sector, drivers are turning to trusted models like the Ford Fiesta, known for their affordability and dependability. With unexpected repair costs a growing concern, choosing a car warranty has never been more important to protect your investment and drive with confidence.

Lawrence Whittaker, CEO of Warrantywise, commented: “It’s great to see not only the used car market at a five-year high, but also the Ford Fiesta to top yet another chart. It has always been a favourite among used car buyers, and recent insight only reinforces its status as a trusted option when looking for a used car.
“The latest figures from the SMMT underscore the unique challenges we face today. We’re still navigating the aftermath of the pandemic and grappling with an economic downturn that sees costs escalating at every turn. This has led to a surge in demand for used cars as consumers opt for more budget-friendly options over purchasing new vehicles. Cars like the beloved Ford Fiesta.
“Many of the used cars are sold at independent dealers, rather than main dealerships, or fall outside the manufacturer’s warranty coverage. I cannot stress enough how important it is to ensure that these vehicles are protected with a used car warranty to prevent unexpected bills.”
