How do I set myself apart from all these other... girls?

Well, yep, here's the story: I met this guy tho other day and we instantly clicked and are like best friends now, today we went to the movies with friends (NOT a date) and he drove me. IN HIS MUSTANG. I was all like, OH GEEZ MAN, and jumped in..... Anyways, as awesome as that was, we are just friends and I do NOT have an intention of dating him, considering we only met a few days ago. But a lot of girls like him, and we are such good friends already I don't want him to forget about me, ya know? He isn't like a girl chasing or anything he is a really nice guy, hence all the girls chasing his tail. Well, anyways, anyone have any tips to keep a guys attention?
