Please could someone tell me what my car is worth it has the following problems:

Someone has disconnected the 4h button
the runners in the rear side windows are rusty
Towbar needs to be taken off and welded
floor of the fourtrak needs welding quite large rust holes
Sills need doing although Im not sure how bad they are

good points

Engine and gearbox seem fine
all the electrics work except the reverse lights dont work and also the holder for the fog light bulb has perished.

Please could someone give me an idea on what my car is worth as im thinking of selling as the welding work onit just seems to much work.
