Good idea to start with a BMW because basically 240s are the best (easiest) cars to drift with. So starting with a BMW is good because you'll get your S14 and it'll be WAY easier
I wouldn't knock it too bad man, I've seen some nice ones before. Takes a lot of custom work though.. Dude, you'll love that S14 though, you might wanna practice your drifting before you get it, it would suck to wreck it ya know
