Oh wait it out for sure. It's only been two years and he isn't even half way. You'll get it back in no time... As in there is No Time you'll ever get it back except maybe the present.
So what if you might expect him to take a while and at even a measly $20/HR (thats IS how much your paying him right?) how long can it take?
More than the price of a new hood and fenders plus a year or two? Those panels might run you $1500 and as fast as he's going you wouldn't have to come up with the bread till there's a new president and who knows... He might be so rich he'll pay the guy off for you.
Sorry just offering a different perspective... It's really all up to you.

Give me ambiguity
or give me something else
