drive it and enjoy it. i wouldn't do alot,except maybe some new shoes the extra room and fuel economy will come in handy.
the guy that posted that 4-doors aren't worth dirt,is not far from the truth.
and anybody that scolded him for saying so,is full of it.
you won't pay anything for a 4-door either. it's the market,not personnal opinion. you can have this car,in this condition,and the same car in a 2-door,rusted and missing engine/trans,and the 2-door is still worth 3-4 times more in the eyes of about anybody out there buying.period. why do you think there are so many really nice (of any brand) pre-1980 4-door cars out there for sale and not selling?
if you need a good,reliable,and more classc looking car to drive. these old 4-doors are great. but,if thats not your intentions,then they are just a real good parts car for a 2-door that needs the parts.
