To be fair I haven't seen any specific dimensions especially length for the official BeamNG vanilla vehicles on the official wiki both old and new. Here is my estimate for some of them for example: Ibishu Pessima 2nd gen: 175 inches long Civetta Bolide: 170 inches long Gavril Grand Marshall: 190 inches long Hirochi SBR4: 168 inches long Hirochi Sunburst: 176 inches long Thoughts?
Depends on the size of your screen and what camera angle it is. On my screen in 3rd person a Roamer is about 13cm wide and 26cm long
