nice car, beautiful look. But little disappointing in CNG version

Everything (buying and driving upto 20000 Km.) was smooth till i have not gone for modify it into CNG. Everthing now is poor looking. engine power is looking less . its silent engine now producing sound. service experience were nice all the time in Bahadurgarh . But now most of the showrooms and service centres have been closed in Jhajjar Distt haryana by the Maruti Suzuki.
