fundamentally unit body is superior, you could make a unibody truck chassis which was more substantial in the traditional frame rail areas but better integrated with the rest of the structure for example. There is no attribute of a BOF vehicle that you couldn't improve (except cost/repairability) with the appropriate unitbody version

in practice implementation is more important than fundamentals, however.


I do not think you can get A bof car anymore. The last gen crownvic was the end of the type In the US I think. Even BOF SUVs are getting more rare. Only the big truck based ones are BOF. It would not surprise me that much if pickups and larger SUVs head that direction as well eventually
