Mario Andretti...a well hated pin.  
I started with a great cab and board set and wasted Playfield.
Installed nos PF- lockdown-legs-glass-cars-cellar ramp and more stuff.
Started out $800 US ended around 1400 ish.  Tried to sell it ranging from 1200 to 1900 shipped.
Sold at $1600.  Sad thing is the guy got out of the hobby and it sold at an auction for $800.
Almost bought it back.

Baby Pac
Another black sheep in the pinball world.
New side art, trim bezel art and I am in the process of clearing the playfield.
Hated by some loved at my house.   Will have 1100 +/- by the end of the project.

Cactus Jacks.
It was wiped out when I got it...missing parts-ramps- wireforms -no legs- cab fade wear.
I sourced a used PF..touched it up cleared it. Got ramps and needed plastics new translite. Sourced a wire form off of the original whitewood owner off of rgp had it chromed (bare steel proto). Painted the cab and sold for a $150 proffit   Now it lives in another collectors house and he loves it.   That restore is the biggest pay off becasue its still semi local to me and I know the now second owner since restore.  Fun game would have been better with a three ball multi. Oh yea got it for $150 sold it for $900
