Rolls-Royce Cullinan.
What to Check Before Buying.

The Rolls-Royce Cullinan is the marque's first SUV, launched in 2018 as the ultimate luxury all-terrain vehicle. Most examples are used lightly by owners who maintain them through official Rolls-Royce dealers, though the complexity of the air suspension, electronics, and bespoke systems means potential issues can be eye-wateringly expensive. Buyers should verify full service history, check the condition of adaptive air suspension components, and ensure all electronic systems function correctly. Given the typical purchase price and running costs, thorough pre-purchase inspection is essential.
