I am having Sunny Nissan XL, 2012 September model.
I have been using Vibrant Nissan Gachibowli service center for last 4+ years i.e 2014.
They have all required facilities for your car need. Premise is well equipped with CCTVs.
Free car pick and drop facility is available from / to home / service center.
For their regular customers, they offer some services complimentary. They keep on having either free or discounted campaign, which we get to know thru SMS.
One of the best service center in Hitech City area.
