Cultus under 1.2 million

Hi I'm a fresh grad software developer and have spared some cash want to get myself a car, friends joke about Mehran and I personally don't like it as well, been seeing stuff on TikTok lately n figured an older cultus could be a good option for me. It's my first time buying a car need some advises, tips, especially will it survive 300km journeys as I might have to travel to Lahore occasionally from my hometown, dealers like dogar motors on TikTok appease me but I think I should get it inspected from pakwheels as well. No idea about documentations as well what to do how to transfer ownership etc

Please help w these queries n what to watch out for in cultus n also suggest vendors
