Yeah dont think will do the pinstripe really be to much blue as said just gunna do small touches to blend the wheels in better.
*Grill Slats
*Wing Mirrors
*Rear boot badge

This is what my suggestion would be: (can tell me to fook off as it's your car!

)
Grill Slats - Silver
Wing mirrors - Silver
Rear Boot Badge - Blue
Roof - Blue and Silver Chequered
That way you will keep the blue in layers rather then spread out.
Shady - can you do a photoshop of all the suggestion? Don't say you don't have time as you can make a sandwich and then start a thread about it
