The best way to determine how high maintenance a vehicle may be in the long-term is to look at the service schedule. This will be clearly outlined by a manufacturer on their website, and by the dealer.
Ford’s entire range, including the Fiesta, Focus, Puma, Mustang, Everest, Escape and Ranger requires servicing every 12-months, or for every 15,000km driven.
These 12-month/15,000km service intervals are very much an industry standard, especially for vehicles that are fitted with a turbocharger that often require more frequent checks to ensure the engine is working perfectly.
