I'll gladly help out on rusty/mismatched body panels if this should be considered!
We could do it like say an S13 costs $6k new, the junked one could be like $3k but it needs to have an engine put in. Swaps would be normal cost, but the stock engine could be like $1k, making it still worth getting the junker as it comes in at $4k total.
They could also be more enticing, sometimes equipped with aftermarket wheels/bodykits/etc.
Of course only mods could submit "junkers" to the yard, and what they're equipped with. If this happens, those mods can feel free to contact me about covering it in rust/etc beforehand if they like!
