The Custom Volkswagen Beetle is a modified version of the Volkswagen Beetle production car. Because of the split rear window in Germany, this car is called "Brezelkäfer" (Pretzelbug).
When introduced, this casting featured an opening engine cover; the cover was molded shut some time in 2008 or 2009. In 2016, the tooling for the Custom Volkswagen Beetle was changed while the Volkswagen 5-Pack was being produced. In the middle of the production run, the Custom Beetle's "sunroof" was closed up and replaced with a roof rack, the large "stinger" exhaust was removed and replaced with dual exhausts that are part of the interior and the base changed to plastic. Due to this, it is possible to find two variants of the pack, where the Custom Beetle has either the large exhaust, metal base and sunroof or a roof rack, plastic base and dual exhausts.
