It’s a long shot, but do you know?

For years now I’m coming back to this memory of a movie. I was a kid when it was running on tv (2000-2007 is my guess). The original was in English.
All I can remember is it was about a young girl and guy. They fell in love, he had a car – I think it was brown or red, but memory is foggy on this. After some time, they kissed in that car, but she had her eyes opened. Then he realised she doesn’t love him anymore. Can’t remember much about the girl, but I believe that the guy had longer, dirty blond hair.

I know it’s not a lot, but if anyone has any suggestions, I’ll take it.
