Instructions
Travel to the southeastern quadrant of Las Venturas. There, you'll find the Camel's Toe, a gaudy pyramid-shaped casino. You'll find the Euros parked under the Sphinx's head. Approach the door and click the action button to pick the lock and hotwire the vehicle. It's all yours now.
Go to the Corvin Stadium in San Fierro. Speak with the manager to enter the derby. Beat your opponents. Once you win, you'll unlock the Bloodring Banger, one of the most durable cars in the game. It will be parked outside of the stadium. You don't even have to steal it. Just open the door and you can drive it away.
Play through the main quest until you complete the mission "Zeroing In," which entails waylaying another thief for her Uranus. When you get the mission, she'll appear on your mini-map, fleeing the city. Pursue her and ram the back of her car. She will stop and run away on foot. After you finish the mission, drop the Uranus off at Xoomer Garage, which is found along the border between downtown and Doherty in San Fierro. Return later to find the Uranus parked next door, ready to ride.
Drive to the Big Ear in Los Santos. The Big Ear is the enormous satellite which you can see from any spot on the Los Santos map. Beneath the satellite, you'll find the one-of-kind Sandking, the best off-roading Suburban in the game. Just click the action button on the door to pick the lock and hotwire your new ride.
