While looking through classified adds for cars I came across one and the person put. "Sunroof well maintained"

This leads me to believe my sunroof is not well maintained, because i've never touched it, other than to open it.

SO what can I do to make sure the sunroof works well everytime ?

and doesnt leak... which it hasn't yet btw.

 

i think maybe he forgot a comma and he meant it has a sunroof and the car was well maintaind
