For starters your side signals are missing!!!! Then you are missing a decent engine...... lol
I would defo go for different wheels and possibly lower it slightly more at least at the front.
I would also add a spoiler possibly a highmounted one at the rear and a lip spoiler on the trunk. Other than that thats a decent looking car you got there!
Just look at Spoony for inspiration on his signature!!
"Lo there do I see my father.
Lo there do I see my mother.
Lo there do I see my brothers and my sisters.
Lo there do I see the line of my people back to the beginning.
Lo they do call to me
they bid me take my place among them in the Halls of Valhalla,
where the brave may live forever"
