Easy Smithers Race (1st Level)

On the last mission of the 1st level, you have to race Smithers through most of the level to get to Mr. Burns' mansion, starting from the nuclear power plant. You can't cut through the power plant itself because a door slams shut, blocking your way. HOWEVER, if you park your car halfway into the doorway (I used the Family Sedan), The door will slam shut on it, damaging it but not destroying it. The rear end of the vehicle hangs out and you can hop right in to take an easy short-cut to the end of the mission without a hassle.

Destroy Cars without getting a Hit and Run

I discovered this when I had already beaten the game the first time. What you do is crash alot of cars and cause enough destruction until you do get a Hit and Run. Then, immediately go to mission select and select any mission from the list (I'm not sure if you have to stay on the same level or not). When the mission loads up, you'll notice your Hit and Run meter is still flashing as though the cops are chasing you, yet there are no cops! Jump in your vehicle before the meter runs back down and start smashing! The meter will continue to refill and stay flashing, but you will NOT get a Hit and Run and the cops will NOT chase you! Now you can destroy as many cars and items as you want for some quick cash - this was vital for me in completing the game quickly to 100%. Just don't let that meter fall below the flashing point or you'll have to repeat the whole process!

Drive a flaming car

To drive a flaming car you first have to choose the car you want. Then crash it until the smoke coming out of your car is black. Then go to a phone and select the car you chose. It should say ''damaged: 100 percent.'' If not crash a bit more. If it does say 100 percent, choose the car. The car will be on fire and you can drive it around, but if you hit anything it will explode.

Glitch House

Go to the 3rd level. Then go to the huge jump that lands you on the harbor.Follow the road you land on until the ship, C-Spanker, comes into veiw. Now go east until you get to Davey Jones Hamper.

Smithers race glitch

On level 1 mission 7 when it says talk to carl, instead of talking to him run over him and push him into the power plant. Park your car inside the power plant and talk to him (It will look like you are outside but you will still be in the power plant). Get back in your car and drive out the back side of the power plant and go to Mr. Burns mansion. Smithers will not be anwhere near the mansion and you will win.

Infinite coins from Buzz Cola crates

When you come up to a Buzz Cola crate or vending machine, DO NOT DESTROY IT. Instead, kick it twice and then collect the coins and leave. Go around the level and do this for all the Buzz Cola crates and vending machines. Save and exit your game, then reload the same level. Since you didn't destroy the Buzz Cola crates, they will still be there and you can repeat the trick over and over to get easy coins without wrecking other vehicles and risking a Hit and Run.

As long as you don't destroy the crates the game will not know that you took coins from it and will "reset" the crate, allowing you to get an unlimited number of coins from the same crates.

Unlimited-coin Buzz Cola crate

In lvl 2, the building behind Moe's Tavern (looking at door side) has a little jut-out on the left with a Buzz Cola crate on it. Unlike other cola crates, this one comes back and you can destroy it over and over again.

Drive cars in missions you're not supposed to.

Suppose you're in Level 1, the mission where you have to destroy Mr. Smithers' car with the Plow King. During this mission, all you have to do is drive to a phone booth and get out. A 10 second timer should start. Before the timer runs out, call another car you want to use, such as the Family Sedan, from the booth. The timer will run out, and you'll get the "Retry Mission" screen. Select yes, and you'll be able to repeat the mission, but in the car you called from the booth instead of Plow King.

In level 5, mission 5, "Never Trust a Snake" (a notoriously difficult mission with a very strict time limit), you can glitch the timer and cause it to freeze. First, talk to Snake to activate the mission, then get into your vehicle. As soon as the mission starts and the timer appears, get out of your vehicle and run into the DMV. You will automatically fail the mission as soon as you enter the building, and will be given the option to retry; select "yes". When you respawn outside, get straight into your vehicle again. The timer will now be frozen, giving you unlimited time to complete the mission.
