For anyone who knows anything about the GTA4 game, you should know that there are a ton of great cars in this game. One of the best would be the Infernus. As you may know, you can only get one through the game, as others are so rare that they're near impossible to find. A trick to get more beautiful cars such as the Infernus is to actually drive it near any ones of your safe houses. This GREATLY increases the chances of randomly running into other Infernus'. The best places to look, aside from the streets, are in parking lots. If the parking lots are big enough, the same car you're driving is almost assured.
