I agree with everybody here in saying you did good. If your planning the build up yourself, you’ll be way ahead. If you take this trailer full of stuff to a shop to finish, you’ll likely lose in the end. Nice find btw!
I bought my rusted out pos firebird over 30 years
ago as a race car.. spent so much countless hours and
money on the car that I have come to love it... it has won
a whole bunch of events but I have to say the biggest thing
is I built and rebuilt the car... it becomes a part of you after
a while..
If you are just looking for an investment you did good if
you can finish it yourself... I would ask yourself is it really
something you want and will enjoy? If you just want to
make money on it you better sell it now as they all take
time and effort
