How do you spawn a grotti turismo on gta 5 online?

To spawn a Grotti Turismo in GTA Online, you cannot summon it directly as it's not a vehicle you can call in like personal vehicles. Instead, you can find it parked in specific locations around Los Santos, or you can purchase it from the Legendary Motorsport website in-game for $500,000. Once you own one, you can store it in your garage and spawn it whenever you need.
