Older movie, man drives off

There was a older movie (not sure 80s-90s) where a man drive off in convertible, shades on, alone, grabbed the steering wheel with his left hand close to end of the movie. Theres also a segment where a man found something under the tree, it was a little box, Sadly that's what I recall from the movie, I hope you guys can guess what was the name of the it.
