I don't know what it is but I've never seen a pin stripe on a G6 that actually looked good and made flowed well with the body line. I agree in saying, remove it. haha
New wheels would be a good step too.
And I'd say... LOWER IT! haha
The stance will look WAY better. plus a lowered car can pull of a lot more exterior modifications then a silly tall one.
But going on what you originally posted. I like the painted pieces, Looks good actually seeing it from a bit of a distance with the cars body in view. I didn't know the base 2.4 came with different engine covers. My engine cover and intake was all one piece... Needless to say it's gone now! lol
