Sell the parts like someone else said and get the car back to stock for sale. In meantime save your cash for your next vehicle / build. Donāt toss anymore cash into this car.
Just my two cents.
Do not make that dealā¦. Thatās a crap ton of miles. Maybe if he had 16k on the car $46,000 okay but thatās wayyyyyy too many miles on a car for the $$$$
