My First car

Hi guys this is probably the farthest Ive gotten on car modeling but this was supposed to be a Saleen S7 but my background image kept confusing me, so this is what i got so far.

I’ve also noticed when I try to model cars the views that mess me up the most are front and back. Any suggestions?. Also you see in side view where I havent completed the side panel as it goes into the car, how do I go about doing this.

Also until I get better aquanted with modeling cars, this is to remain a work in progress, BTW the person that inspired me to start modeling cars would probably be katalon.
Any video tuts on modeling like katalon does would be greatly appreciated.

Thank You
