Thank you Dharmesh,Appu,Akash for your inputs.
Yes you are right Akash, Spoiler will change the looks, I will try to locate the clips one. Yes black painted rims will enhance the looks of the Wheel caps in silver !! otherwise wheel caps silver color mix up with the rims silver color and wheel caps design is not visible.
But believe me, it is maybe my subjective conservative feel that it always looks painful to me to disturb the original colors and set up.
Than DIY, I prefer to go to a painting expert though I have a paint shop in my industry itself. You know painting is an art on different metals right from preparing the surface and selecting the compatible paint to have the kind of shine !!
You know I look for a professionalism in everything like a saying "it is always better that A dog & donkey have their own expertise and should stick to it".
No offence for our members doing DIY(yes that is their passion hence everything comes out well, even if something goes wrong they do not feel bad and try again to set it right) as my own experience of doing DIY on something else backfired
some times.
Thank you all for your kind suggestions and you will see some different pics of my Ritz very soon !!
