dude 1st sort out the main thing, u need a manual transmission car or auto transmission? then sort out what are your fuel consumption priorities....if u really want a fuel economy....buy the refurbished cars like Daihatsu mira, Suzuki alto, Daihatsu boon (its copy of passo but with 1000cc engine instead of 1300cc), Suzuki kei....these cars have better built than local assembled cars and give better mileage, u don't even have to install cng on these cars. mostly they are 650 to 800 cc only. but if u don't have fuel economy problem....the best car in my opinion is Honda city. its true that its really hard to get a good maintained city, the reason is that its so much comfortable and luxury with fuel economy in its class that owner of city don't sell their cars that often as compared to corolla xli/gli. I don't know about manual, but I have vario 2005, 65000km done, I bought it for 7.5 lacs after negotiation. no work at all required. but I waited for it about 5 months in searching. its comfortable, luxury, powerful, give economy around 10 - 12km in Karachi city. I have owned santro, se saloon, liana and swift but no one matches the package city is offering. I haven't installed cng, I m using it on petrol. plus I m happy to get such a huge large trunk space (DIGGI), really don't know what to do there, may be sit with my friend, relax and have a tea!
