We'll consider adding language links to the front page once the wiki activity and amount of translated pages get to a high enough level. Alternatively; we could make translated subpages for existing articles. For example: the translated page for Satsuma could be Satsuma/de, which would be linked to from the original page.
If you're using auto-clutch, try disabling it and using the clutch manually (the auto-clutch is known to not work very well sometimes). The car might also simply have broken parts or loose bolts, did you use a guide to build your Satsuma?
