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). The no split-window one is called "Ovalikäfer" (ovallybug). 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 massive exhaust was removed and replaced with dual exhausts that are part of the interior, and the base was changed to plastic, likely due to cost cutting; due to this, it is possible to find two variants of the pack, where the Custom Beetle has either the massive exhaust, metal base and sunroof or a roof rack, plastic base
