You didn't completely finish the name change, for Adam/Josh.

If he has unremarkable eyes, don't start out calling them blue. Better yet, don't mention their color at all. Blue eyes really spark a mental image, and it's hard to get out of your head.

"The curious boy"? Your tone isn't harking back to Alice in Wonderland, so don't use "curious" that way.

I don't know much about cars, but what's with the Volvo? Usually teenagers don't have much choice in their cars. I'd mention the car's condition or color or some visual quality as well as the pet name and how long he'd had the car or where he got it rather than mentioning the make.

What did he do (instead of driving around for three hours) before getting his license? Pre-AP English would be tenth grade, so if tall-guy's in the same grade as the narrator and hasn't been held back, he can't have been driving before the school year started.

I like your general narrative style and your use of repetition, but I think your story would be really great with more work on tone and choice of details.
