Popular Earth vehicle alternate modes

When on Earth, a Transformer typically finds a wide variety of human vehicles matching their general body plan and size available to adopt as a disguise mode. Although there are many thousands of options available, certain specific models of vehicle, however, are very popular disguises, seeing repeated use across multiple individuals and continuities.

TFWiki.net: The Transformers Wiki has certain requirements for a vehicle model to be listed here. There must be at least three unique toy molds (or in-fiction appearances, in the case of non-toy bodies/characters) that share the model. There must also be at least one unique character per mold. Certain models are "lumped" together, such as the case for the Mazda RX car series, which includes the RX-7 and RX-8 types. This also, of course, takes into account the various fudging of the designs that are done in order to get a robot mode out of the toy, as well as avoid having to pay a licensing fee to the actual manufacturers (in most instances).

Each mold is listed on its own line, with all different-character decoes/retools on the same line. The list is organized in chronological order of toy release.

This policy is in place mainly due to the rampant use of redecoes as new characters, and is a little out of line with the phenomenon being explored... after all, isn't it kinda weird that out of all the myriad types of fighter jet there are in the world, that the Dassault Rafale in particular seems to pop up so often across soooooo many jet-form toy-characters?
