I'm telling this to you from a first hand owner experience of a 1300 cc RXI Liana. The car is an absolute disaster, we bought one in May 2006 and kept it until 2012, not a single week went by without the car causing some kind of trouble, we tried everything, all dealerships across Sindh and South Punjab, other reputed mechanics such as Khan motors and Kalu in Hyderabad but it was impossible to make it work. But I believe the problem with Liana was its incompatibility with CNG. Even after the experience of owning such a ridiculous car, I'm inclined to buy a petrol only driven Vurv model and give it a try. Eminent was the top of the line model and it was also available in 2006 and I've heard that it ran decently due to a 1600cc engine unlike RXI. There are a few 2005-06 imported Liana cars available in the market and they run just fine on petrol and CNG. A consignment of Liana cars was imported by PakSuzuki in 2005 and they were readily available at showrooms against a minimal Premium.
