Now we're getting somewhere... information is key...
there are definitely 2 routes to go... if there is rust and repair work needed, but things are generally y solid, AND you have all the service history (not sure how long you have owned it for). You may be better off selling as is, it may be a great starter for someone wanting to do a big restoration. All depends on how much work it currently needs, and who would be doing it.
Looking forward to photos in detail
