The Rolls-Royce Cullinan is the most luxurious SUV you can buy today. Even in the standard form, it basically has everything one needs (and doesn’t need) in an SUV. But that didn’t stop aftermarket companies from trying to do different things to it and give it a twist.Klassen stretched and armored a Cullinan and put a $2 million price tag on it. Rolls-Royce upped the ante when it launched the Cullinan Black Badge edition. And, now, Mansory has laid its hands on it and unveiled the Rolls-Royce Cullinan Coastline.
