I seriously hope this does not look like what it seems. You didn't actually get in this guy's car did you? As you posted it sounds like some stranger pulled up and started insisting he take you to the store and I sure hope I'm misunderstanding because in all honesty that is inviting problems hun. Some guy pulls over and starts wanting you to get in his car ummm run away. Run away fast. The context of the things he said are completely irrelevant, he's a creep.
