Since 2019, after complaints from Cact0 and TheGreenKangaroo, JMinibys 1A and J Class A1 and Class G1 have been removed from JM's lineup, but remain in the wiki.

On 17 July 2021, the Aviation Division was sold to Stratus Aircraft. Weier became a co-CEO of the new company.

JM financial building
JM financial building in Savage City/Willow

Sunshine Coast Factory

This was quite a challenge, as the factory was built under the SSC Beltway and currently produces crucial engine parts and the J Minibys 1B. It is more modern and slightly aesthetically pleasing.

Savage City/Willow JM Campus

A large portion of Savage City holds buildings and industrial infrastructure that belong to Jupiter Motors. The factory is situated west of Old Town, south of YellowSpork and between SEAT's Savagebite line and the W-5. Later on, the Campus will become the largest installment of JM's factories.
