>>10611145why would you build garbage just to save a handful of dollars?
at least buy a model that you'll be able to appreciate at the end.
For the sort of exercise you've described, I recommend something like the Rosomak APC. A big, boring box without prominent features (flat surface) but a lot of different panels.
This is because it will force you to employ every trick on the playbook to make it even remotely interesting, and you also need to create a balanced composition, which is not easy.
I also suggest you go all out instead of being timid just because the real vehicles are always kept in a pristine state.
