Cartax

The Wattersons' Cars have appeared in a few episodes of The Amazing World of Gumball. It serves as the family car, and most of the time, Nicole is the driver.

The Minivan

 * The Minivan strongly resembles a 1984 Dodge Caravan.
 * The only difference is that they have sliding doors on both sides, while the real world counterpart has one sliding door on one side of the vehicle.
 * The "Classic" badging on the Minivan is similar to the Cadillac script - considering there is another company also based on Cadillac (Marliac, the manufacturer of the Robinsons' car), the company may be based on Chrysler.
 * This car is always seen without a license plate (which is illegal).
 * Like the black sedan, the minivan is also driven by other people in Elmore.
 * "The Goons": It appears in traffic.
 * "The Remote": Nicole jumps onto it while at the car park.
 * "The Bumpkin": It is seen being driven by the Cupcake Woman on the highway, when Richard is driving the kids to school.
 * "The Flakers": It sank in a pool after Richard drove the car into it.
 * "The Authority": It is seen being driven by Mrs. Wilson, before crashing at a junction.
 * "The Kids": It can be seen during "Make The Most of It."
 * "The Gripes": It's parked at the parking lot.
 * There's also another car that is the same model driving around Elmore, but has a different color (two-tone tan and white).
 * Nicole drives the minivan again in "The Password," when chasing Richard to find out if he really is a bad cop. The door handles are now on the right side of the rear doors, and the "Classic" badging on the front doors is omitted, making it a generic American station wagon-esque MPV.

Station Wagon (Season 1)

 * The Season 1 Station Wagon resembles a 2nd generation Pontiac Grand Safari, with a front end similar to an early 1960's Pontiac, and a rear end similar to a 1st generation Pontiac Grand Safari.
 * The front license plate number is "ODH 22."
 * The back of the car has a missing license plate (which is illegal), but, instead, a graffiti'd plate that says: "ARRST."
 * The badging on the rear door of the Season 1 Station Wagon says "GUMBALL" on it, hence the character and the show's name.
 * In "The Painting," the car appeared to have slid into another car, but it is unknown what happened afterwards since the scene shifted as soon as the crash was heard.
 * In "The Ape," the car gets an epic role of the chase for Miss Simian.

Station Wagon (Seasons 2/3)

 * The Seasons 2/3 Station Wagon is a 1978 Ford Fairmont Squire, with the front and rear fascias of a 1977 Ford Pinto Squire.
 * The front and rear license plate number is "ODH 22."
 * In "The Treasure," in Richard's flashback after he accidentally clicked "Yes" at the Stellar Corporation website, the Season 2 station wagon was next to him, meaning that he and Nicole bought the car before Gumball was born.

Black Sedan

 * The black Sedan is mostly based on the late 1980s Ford LTD Crown Victoria.
 * The license plate number is "X23 TU," which is the same as any other black sedan in Elmore.
 * In "The Authority," it is revealed that the Wattersons' also own the black Sedan. Granny Jojo seems to be the main owner of the car, though, it could be a replacement to the minivan that is now seen being driven by other people in Elmore.

Trivia

 * The scene where Nicole shift gears in "The Ape" and "The Authority" is the same, even though the cars are different.
