Centralization will build ladas and vw beetles and skodas. Practical on the day to day.

 Now decentralization will build you crazy stuff like lambos and Bentley's, Monster trucks and suv and ATV. Specialist stuff for environments the sensibles cant handle.

So as long as you dont mind crashing, getting stuck or being left behind in non standard conditions (may not happen often) then yes central is more efficient and easier to staff.
