Storage find 1967 dodge dart

I was fortunate enough to be able to buy a 1967 dodge dart w/ 22 thousand original miles & original yellow paint. it was a storage wars type find, the only thing that is not original is an add on tach & Cragars . 8 cyl. 273,it has factory air, bench seats , the interior is like new,Auto on the column , factory tint windows, the undercarriage is awesome , no rust anywhere except a very little surface on hood lip, but it's just surface rust. body & molding some are awesome as well (a few car door dings)...
Now here is my want VS concerns ..
As a kid I had a 67 dart gt , it had buckets ,center console . .. I just bought bucket seats, console , shifter & linkage , mounting bracket & template , NOW what is the pros & cons of taking a 47 years old original car vs changing it to a sporty looking car. what is the value difference . .
