Basically, I start off by making the car body as one, fairly low polygon shape that I then separate into smaller pieces and cut them out. However, you must make sure that you're happy with the overall mesh before splitting it, shaping it later becomes difficult because you now have multiple pieces that will no longer match if you edit one.
I've included an attachment to show how I work, you can also see the problem I mentioned at the edge of bonnet where it doesn't quite match up with the car body. Gotta fix that one I resume work on this particular model, but it's still fairly low-poly which makes it easy to correct.
Okay guys! So i finished the Fzr project for now And its available for public download,so if you like it,feel free to use it
