Thanks everyone....
* car seats were re- formed with leather covers
* for the upholstery, kept the original covers with new hard boars inside.
* headlights were replaced
* emission system fully replaced
* shell replaced with b210 shell which I thought would be more suitable
* most of all, Air conditioning system implemented few days ago.
I thought of NOT changing the original look of the car, but please suggest anything to get my ride to a better stage. Your valuable comments are always welcome...
