KSI was one of the original members of The Sidemen, a group of seven British YouTubers who launched a premium web series in 2018.

KSI addressed this incident in his autobiography, KSI: I Am A B*****d, released in 2015.

KSI made an extravagant purchase of a customized £280,000 Lamborghini Aventador in 2014, which he proudly refers to as his “pride and joy.”

This exquisite Italian sports car was uniquely wrapped in a striking purple by celebrity car customizer Yiannimize.

He even released a track called Lamborghini in March 2015, celebrating his beloved vehicle and featuring it prominently in the music video.

Nevertheless, reports suggest he sold the eye-catching car at a loss two years after its music video release.

Recently, KSI has moved on but still enjoys his Porsche 718 Boxster, which he bought in April 2019.

This sleek vehicle, priced at about £65,000, has a convertible roof and can reach a top speed of 171mph.

He personalized his license plate to read “K51 FLY,” ensuring that his presence is known on the road.

Although he has shown off this exclusive car in various Snapchat stories, no exterior photos have surfaced.

The Cayenne is celebrated as the more luxurious option in Porsche’s SUV lineup, featuring a 3.0L Turbo V6 engine.
