Sir you appear to be a reasonable person, there are folks who are demanding 800000 rs for 2014 year bolan, but does it really matter? There are ones who are demanding 730000 rs for 2014 unregistered bolan. Why in the world would someone pay extra for a 2012 bolan, its really hard to comprehend, I asked Suzuki Motors a few days back as I am buying a new one, and the gentleman told me that it will cost me 695000 plus 4900 for insurance I guess, the company has even weaved off transportation charges and the wait period is 20-40 days. Now I think one can easily install CNG on any EFI car, all newer model cars are EFi and they have been fitted with CNG and they give even a better millage then the carburetor ones. Once again I apologist for giving any wrong interpretation in case , of this subject, and would listen to your argument if it really is worth it.
