Parkside Southern Brake Van

I had a really busy weekend this weekend and one the things that I made much progress on was the SR Brake van that I started earlier in the thread.
After work today I gave it blast of primer and here it is.

Now I have a bit of a dilemma, I plan to sell it once it’s finished (I bought it specifically to build and sell on as I neither model BR or the Southern) and I have seen examples with both screw and 3 link coupling and I am unsure which to add – If I add screw couplings it will add another £5 to the price.
Similarly with a stove, if I add a cast stove it will again add another £5 to the cost. without my adding anything for the assembly etc. of them.
If you were a buyer would you prefer screw couplings and a stove or to get the van £10 cheaper?
