Both these models reproduce the same version of the '68 Ford Mustang, the GT390. However, differences exist and they are not few! But now watch the following pictures that depict them side by side (on the left the model produced by ERTL, on the right the model produced by AutoArt).

   First of all, you may notice that the color of the body is not the same. The paint used by ERTL is a metallic green, while that used by AUTOart is a pastel green. However, the biggest differences are in the front, in the back and inside the cars. Here we will see in detail these differences.

   The shape of the hoods is almost identical: both veins and air vents are the same size. Only the slots located at the base of the windscreen are finished better on the model produced by AUTOart.

   Looking more closely the hoods, you may notice that the AUTOart is more detailed, especially regarding the 2 air vents in the center of the hood: in fact, thse elements are drilled through and created by photoengraving.

   By opening the trunks, the 2 engines appears: the ERTL is little detailed and it's composed of few elements, while the AUTOart is very detailed and it's characterized by the presence of several components (including complex wiring).

   The frontal parts of the 2 cars (as I mentioned at the beginning of this article) are completely different: the AUTOart is accurate and it perfectly reproduces the forms of the real car; instead the ERTL is quite inaccurate and very simple (it looks like a toy!)

   Looking into the details of the front parts, we easily see the flaws in the model produced by the ERTL: the headlights are dull and there aren't the chrome-plated frames, the central air intake is not perforated and the tires are too thin.

   Even the back is not without flaws: first of all, there is a matt black paint (absent from the real car used in the movie "Bullit"), it miss the word MUSTANG on the trunk and the chrome frames are missing around the rear lights.

   From the previous pictures you can see how the wheels are well detailed on the AUTOart model: through the rim, in fact, you can see the disc brakes (on the front wheels) and the drum brakes (on the rear wheels); on the ERTL, the rims are filled. Finally, the AUTOart tires are soft while those of ERTL are hard.

   Watching carefully at this picture you can see the incredible detail of the model produced by AUTOart: the rim, the door handle and the lateral air vents seem almost real!

   In the images presented above, you may notice some differences between the two models. First of all, on the ERTL when you open the doors you can see the elbow mechanisms (normally used on toys) while on the AUTOart the doors are connected by hinges. The internal panels on the doors are similar, but those on the AUTOart are slightly better (especially about the levers to lift the glass). The dashboard is much more detailed on the AUTOart (there is even a wood coverage on it) and the floor is covered with carpet. The model produced by ERTL has an incorrect angle of the steering wheel.

   The windows are quite similar, the only things changing are the chrome profiles: on the ERTL model are painted, while on the model of AUTOart are created with a chrome-plated plastic frame. The windshield wipers are reproduced faithfully on both models. On the back window of the model produced by ERTL there is (in the middle) a strange camber which follows the profile of the body (it is a mistake because on the real car it's not present).

   The trunks are perfectly identical with the only difference that on the AUTOart the trunk can be opened, while on the ERTL the trunk is sealed.

   In summary, the lateral views of the 2 models are similar: the ERTL has the front part a little too high, but overall is well done (there is only a little defect, the side lights are simple stickers while on the AUTOart are realized with clear plastic). So if you are searching for the legendary Ford Mustang used by Steve McQueen in the movie "Bullit" my response is: if you look for perfection, you must buy the model produced by AUTOart. Otherwise, if you want a rare model that has the official license from Warner Bros. and the "Bullit" trademark you must buy the model produced by ERTL. Buy both models is for me the right choice!
