TL;DR: I tell my story of how I bought a JM at a premium price, put a lot of money into it, and don't expect to sell at a premium price. As for this WCS, It's still a B-level game at about $4000+ premium price.
My two wooden nickels:
I purchased a JM for a premium price. For the price and the description I was given, I thought it would be a nearly plug and play machine.
1. It gets here with loose nuts, bolts, screws, and fuses in the cabinet bouncing all around.
2. Ground prong cut off the plug.
3. Both ramps have cracks in them where the ball zooms around the loops, and I think the Cliffys will just barely cover them once they come in (prolly looking at a 3 month backlog waiting on those).
4. Bulbs burnt out underneath the PF.
5. Hand has some "skips and stutters".
6. Legs have surface rust all over them (insides of the legs), and the stabilizers are so rusted I almost had to get vice grips outo just to properly level the machine.
7. U20 chip just happens to go bad the very first weekend it is home.
8. Slingshot switches so out of the adjustment the right slingshot nearly goes into "machine gun" mode.
9. Spinner needs new decals.
10. Diverter in the back has scratched the PF due to the nyliner being worn down.
11. Translite damage over the main title of the game.
12. High voltage switch was out of adjustment so game was stuck in constant "coin door open" mode even with it fully shut.
13. Rear left leg bracket was stripped.
And that's just what I found before I left for my assignment here at Point Mugu Naval Air Station. Before I left, I had already installed a new/used translite, swapped out U20, properly adjusted the slingshot switches, done a full LED conversion, installed a new power plug, used bicycle chain grease to lube the Y-rod of the hand - minimizing the skips and stutters, swapped out the rear left leg bracket, and adjusted the high voltage switch. I got the game to where it was at least playable and 100% functional so my family can enjoy it while I am away.
That was a full solid weekend of work and effort. I haven't even got into shop jobs, quickly adding the Cliffys when they come in, taking apart the diverter and putting new parts on it so it stops gouging the playfield, swapping all 4 legs with new ones plus all new hardware for each, or rebuilding the hand when it's time.
I think I have about $200-$300 in parts waiting for me when I get home, and I know I have more to order as I sit here in my hotel room.
I paid a premium price for this game, and look at all the work I am putting into it. Adding a ColorDMD down the road, with all the things I have already mentioned above, do I think I am going to get all my money back in parts, time, and effort? Should I try to sell my JM for $4000+ ?
Absolutely not. You know why? This is a hobby. It's not stocks and bonds. It's not Vegas. It's not a 401K where I expect to yield profit over time.
It's a HOBBY, and the last thing I expect to happen in a hobby is for me to recoup everything I invested into this game. I expect to lose money, pass a nice game onto someone else, and not look in the rear-view mirror about it. It's that simple.
Now, addressing the OP: your game looks the part. When you start talking this level of money, you have two things working against you:
1. Ramps are not brand spanking new.
2. PF has minimal defects (read: it's not a new PF).
Without those two, unless you have someone approach you that wants a WCS this decked out and nice, it is staying in your collection. Pretty simple.
This and that T2 for like $7000 are both examples of games where some incredible love and effort were poured in, and at the end of the day, they are both still B-level games - no matter how much money is thrown into them - just like my JM.
