Regular vehicles (tractor, seeder, harvester) are a level 1 vehicles. Work 2x2. With 2 vehicle parts (each) they'll be upgrade to level 2 (2x3). Plus 5 more vehicle parts they'll be in level 3 vehicle (3x3).

School bus plow --and maybe MW vehicles-- are already at level 3 (3x3). To upgrade to level 4 (3x4) they need 10 more vehicle parts. And 15 vehicle parts more to level 5 vehicles (4x4).
