By observation, some people buy "an old car" (for whatever reason) and then seek to "restore it", suspecting that anything they might need will be at the local auto supply, or some nearby restoration shop. ONLY to discover that C-body Chrysler products are (as is the case, then and now) a breed unto themselves. NOTHING like a similar-year Camaro or Mustang, by a long shot. Then, with those realizations, they might lose interest, with the car still hopefully still in one piece, and go onto something else.
The car looks pretty good, but I know that there might be some issues lurking under that steel skin, which will need some attention, sooner or later. Just the way things go.
In the mean time, DO drive and enjoy the car for what it is. Something more unique than a Mustang, which can provide lots of driving pleasure with reliability and durability. Learn and appreciate the tactile feel and sounds it makes as it drives, which is ONE of the things which make any Chrysler product unique and different from Fords and GMs, which have their own unique feels and such. Back then, there was NO "generic car" as such, unlike how things tend to be now.
Drive the car and learn about it too, as things might present themselves. Things can be better that way! BUT DO Investigate the mechanicals and such, for possibly fewer issues "down the road".
Enjoy!
