King Courtney wants Claude to steal some gang cars so they can do some hits on their enemies. The cars he wants are a Mafia Sentinel, a Yakuza Stinger, and a Diablo Stallion. He wants them in fair quality and doesn't want them wrecked. The cars are taken to a garage in an alleyway in Newport. I've found an easy way to take out the Mafia Sentinel - via the Porter Tunnel without going through Saint Mark's!
