Hmmm...I would have to agree with you on most points,but their are many more mods that need to be addressed with the concept.
First of all,the location of the "air intake",that's gotta go,or be better yet,non-existant.
Where are the "marker lights",need to break up the blandness of solid sheetmetal(catch my drift)?
Change the 30 degree angle of the "grille section"to about 15 degrees.
Remove the corvette lookin' tail lights and replace them with 2 single enlongated tail lamps,and lower them a couple of inch's,and give us a "formed" front and rear bumpers...add some "contours"for crying out loud.
Gotta have a "chin" spoiler up front(RS/SS/Z/28 versions)...fingers crossed:(
Oh,and the "plastic engine cover"...get rid of it!looks very cheap and tacky
My 2 cents
