I only really remember one scene, but the whole movie is essentially around a younger boy (maybe about 16) in love with some girl.
The scene is where this much older male tells the young kid that if a girl really likes him, she will unlock the door for him in the car after he's put her in it, and to go around the back of the car to see if she unlocks the driver side door or not. The older male gives the young kid this "fancy" car to take the girl on a date with.
The movie is an 80s movie and based somwehere East coast.
