If you own or are considering buying a 1993 Leyland Daf 400 Series Diesel Turbo, be prepared for above-average maintenance costs.

Ensure all tyres match the recommended size and load rating. With an average mileage of 118,679 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
