For my 1/32 diorama (for some day...) i bought a Heller 1/35 Jeep. I spend quite some time measuring all different models of Jeep willys to find a model that would be (close to) 1/32.
Heller turns out best fo me, so that isn't an option for yoou I guess.
It does have a trailer, which a nice extra.
For Italeri I remember it to be not entirely correct in size, but much better than the Heller. Better for you that is.
As for kit accuracy and build-ability, no clue.
Another thing I recall: shapes and size differ form model to model very very much. So it was well worth it being regarded (and who to blame?) as a modelling idiot, buying no model, opening every box and measuring some plastic pieces with the ruler behind my right ear...
