Never understood how someone can let a Shelby go this far!! Or any vintage Mustang/Shelby for that fact!!
These people got to know the value of these cars when they're restored. But there is a "point of no return" as to when they think they have an investment, but then the old cancer (rust) gets too far into the meat of the metal and then they're not worth 2 cents (in a matter of speaking)
First off we have no idea of when these pictures were taken but we need to remember that for allot of people (the vast majority out there) these are just cars. Something to be used and then discarded like an old couch or mattress.
At points in the past most (if we are to include non Shelby's) were nothing but transportation and all of them had a point were they were not worth fixing up or maintaining, so owners choose to do what they do with unimportant things they once liked but their time had passed. Scrap yards, poorly stored or yard art....
The vast majority were and still aren't considered a true investment but of course that is another almost endless thread and discussion most of us have seen on forums over the years.
