The other options that you have in this budget are, a corolla ae110, a rare but awesome vehicle, If you're into diesel, my recommendation would be a sunny 95-96 with cd20, best diesel car in 600k price range, but a bit heavy on pocket since the parts are only OEM, unlike Indus. Liana is a big no no. Clean city 00-03 or a decent city 04-07 models are also worth buying in this price range. Indus 1.3, just a bit underpowered but extremely reliable and perfect for daily driving, even on CNG, If you want a hatchback, get a Santro. All these cars are trouble free IMO. There are many other options but parts availability could be an issue.
Liana vurv is not a bad car if you find a petrol driven one. CNG in Liana would be your worst nightmare. But its your risk, nobody would recommend a liana to you. Most mechanics would not even touch it, and trust me, you'd have to visit a lot of them. During my ownership period, I took my Liana to dozens of Suzuki dealerships, from many dealerships in Karachi to hyderabad to Multan to Lahore, nobody was ever able to resolve the issues. it was a '06 Liana rxi, and CNG was the main problem, I guess that was the only efi car I had on CNG, after that we had a Mehran for running the errands but was mostly in drivers hands and trust me I was happy with the Mehran but was never satisfied with the Liana. At least I knew how to work on the engine of Mehran.
