CNG in Hyundai Getz Prime 1.1 GVS Option

Hi all,

I am interested in buying Hyundai Getz Prime 1.1 GVS Option. All I wanted to know that how successful is CNG in Getz versions !!

I am asking this because, I just visited the Hyundai showroom, they are giving warranty on Santro, Accent and i10 on CNG versions (obviously at a extra cost of Rs. 55000 approx)
But NOT on Getz.

Pls suggest.

Thanks and Regards,
VIKAS
