Working on a LR is a labor of love, you will never get what you put into it.

I wouldn't say never. If you find the right buyer, you should be able to get out what you put into it easily (forgetting about labor). The right buyer in a case like this is someone who realizes what has been done, but doesn't want to start with a vehicle in need of all that work and do it themselves (or pay a shop $$$$ to do it). The right buyer is usually not a die-hard Rover guy (or girl) who is constantly wrenching on their vehicle.
I have sold 3 Series Land Rovers over the years, and always ended up on the plus side after the sale.
