If left in a trunk, bouncing around it probably is dinged up. These rifles are well made and with a little tlc most can be brought back to life. Some good gun oil, a Frontier 45 pad for the metal, a good bore scrub and it may be fine as a shooter. If you aren't comfortable cleaning and checking it find a good local gunsmith and let them take a look at it, maybe clean it and test it for you. I hope you can get it ready and enjoy it for years to come.
