Ive kept 3 CNG cars in My Life,
1. Suzuki Mehran:
Bought it Brandnew in 2006 with FF CNG, the car used to gave starting problems, alot of missing, no pick, car used to go to mechanics frequently, drove it for around 20000kms and sold it in 2011 or 12 .
2. Suzuki Alto:
Bought a 2008 Model with FF CNG used in 2012, biggest mistake in my life, the alto manufactured in the year 2008-9 had a factory issue of starting, the bloody car just won't start, showed it to the world but no one could figure out the problem, finally sold it out and was in look for a Chevrolet Joy, i found a only 18000km driven 2011 model FF CNG and surprisingly, its ring pistons were fried . After that bought a Throughout petrol driven car and haven't seen the face of mechanic since 4 years Mash Allah
