I personally love the Margalla, for the price you could buy it for back in the days, there weren't many decent sedans that were available in that price budget. I love how the parts for these older Suzuki cars are cheap and still available.
About the abusing part, that's a sad reality of our country and it's not just with Suzukis, I know people who abuse Hondas and Toyotas as well but that's another story. Zyada log committee daal kr Suzuki khareed lete hain takay ek aisi gaari ajaye jo sastay me ajaye aur 5 log beth kr ek jaga chale jaen. Pakistan me ek myth hai k 'Suzuki ko maintain na bhi karo to chalti rehti hai' which is wrong, every car requires the basic maintenance and if you maintain it right by spending a few bucks, you're basically adding more years to it's life.
About the carburettor, I'm going to look into it but I'm getting the engine overhauled since it's required. Went to Bilal Gunj to source a good motor to swap in but nothing was falling into the budget so I'm going with the overhaul. insha'Allah everyone will see how I'll turn this car into a proper head turner like the rest of my projects so far.
