Cool but try a little variety lol. And not so much black and white.
I like the Challenger photos though

More like #10 would be good. That is my favourite of the lot, probably because it is the only colour one with a decent background hehe
Sepia isn't my favourite of the filters to say the least...

1st No. 12 - Menacing, the car is actually staring you down. I would have put the lights a little further into the top right corner though for extra effect.
2nd No. 10 - Eye catching foreground colour wth dazling light source included for effect.
3rd No. 9 - Striking main object colour on black and white works (especially red & yellow), just ask the Sin City artists.

Why no BMWs? Personally i think the chrome detracts from a picture, if you are taking a picture of a car as the main object, you dont want it to become part of the scenery because it's just reflecting everything around it............or perhaps you do and I'm just missing the grandure of it all!
Drifting makes good videos, but, not photos.

Don't forget, you asked for opinions, don't shoot the messenger!

looks cooool!!!
