Legal advice about a "stolen" muscle car?

Okay lets start from the top-
My Russell worked with a guy named Brendon. Brendon inherited from grandma an old 69 Ford XL 429 thunderjet cruisomatic ford nine inch all together origional motor 49 thou origional miles, doesnt run last licensed in 80'. Russell bought it and recieved a complete bill of sale, an open title from brendon, new license plates in return for $250 for the car. LEGAL- no problems there

Then- Russell sold the car to his fathers friend/co worker Darnel for $1000 and he got the car the open title fron Brendon, and the new plates.

The car was stored out in the boondocks at Darnel's Best friends shop and house, he is named Joe

On joe's property are many valuable but unrestored classic and muscle cars
The property is owned by joe but darnel is "partners" with Joe

one day darnel decides to go around joe and try to buy some of Joes almost purchased land for himself

Now joe and darnel hate eachother and wanna kill eachother- literally

joe begins selling all of darnels cars out of spite, joe says they are his cause they are on his property and Abandoned

learning this Russel doesnt want his car to disappear to some random person some random place in state or further, knowing joe will sell the car with darnels permission or not, and Russel's prized find will be gone forever

so russel agrees with joe to trade a ford truck to joe for the ford car
russel draws up a bill of sale but forgets to have joe sign

ps the ford truck is legally owned by russels best friend stamm, stamm bought the truck for russel when he couldnt afford it and now russel just owes stamm $400 some time later for the truck, no big deal

HOWEVER the bill of sale given to joe is from stamm to joe stating the truck in trade for the car

russel takes posession of the car and several days later confronts darnel for the title and plates

darnel states that the car is legally his and that russel should never have made a deal with joe for something that doesnt belong to him, darnel says that he could call the cops for russel having posession of his stolen car, darnel says to go get your truck back but nothing is specifically mentioned about the car
ps darnel is _friends_ with a repo man....

so russel goes to the court house and discovers lazy darnel never registered the title in his name, in fact the legal owner is Brendon who is in jail/gone from town
so russel finds his bill of sale from brendon and consults a lawyer, lawyer says get a title and the car is legally yours, and , well hold on one sec...

so russel goes to the court house and gets the papers for a bonded title and gets a 40 day sticker for the car, the lawyer said with these things on record if darnel tried to register the car then the court house people would note the records already on file for russel

russel goes to brendons last known residence to no avail, fills out the bonded paperwork, and has the car inspected by a police officer as per requirements of the bonded title

russel goes back to the court house and recieves new license plates registration for the car, and a title will come in the mail in a couple weeks, the car is legally russels

russel is still intimidated from hard feelings from darnel, who is his dads friend/co worker

russel wants no hard feelings and wants darnel to seek his retribution through joe in court etc, cause thats what darnel will have to do anyway for the rest of his many cars already sold and long GONE

Russel really needs help/advice, russel is afraid darnel might do something to the ford or other cars he owns, (darnel threw a bucket of nails all over joes drive way, darnel is also a shady weed dealer..) Russel is 19, please help =(
