Well, I am the owner of Efi Cultus VXL CNG since January 2010 and i got it zero meter. From the first day till today, it is giving me on the average 18+ kmpl in city with AC (on CNG), am talking about Karachi's horrible traffic and Jams inclusive, on petrol Its guarenteed 16 kmpl with AC. I have found it to be one of the most economical and fuel efficient cars of today and the most comfortable one as well. Moreover, for the past four years, it has not given me a single problem with respect to the workmanship or any engine associated trouble. Even the power windows and the power steering is working perfect trouble free. I wish it had an ABS and EBD system with powered side windows, suzuki is offering in Swift. I am more than satisfied with my Cultus and have no plans at all to replace it.
