5 stars? You could maybe say what lets it down?

Nice and simple but awesome style.
The only thing that could be improved is the selections, some a quite jaggered in the hi-res.
If you don't already try and use the pen tool and with a 0.2px or 0.3px feather, it will make it a lot cleaner.
Keep it up!

Like these cars a lot!
And love what you did to it!!

Only thing I don't like is the front grille, let the logo stay or remove the diagonal chrome line too. (but that's just taste)
So great chop!
