IMO a 2 yo vehicle is not an adequate test of how good a brand is. It's a question of the durability of the vehicle after it comes out of warranty, and whether the buyer gets bent over by the manufacturer when the vehicle is older, as the three-pointed Death Star is so famous for doing.
Like you, I have owned a range of brands in the space of 60 years. I would have to class Mitsubishi as one of the most underrated brands around, several of their vehicles I passed on to others went past 400K on the odometer with no problem. Nissan had a stellar reputation with the Sunny, but their adoption of CVT has cost them dearly.
Financially, the most sensible thing a new car buyer can do is drive the vehicle into the ground. It makes least sense financially to be trading in a vehicle which is only two or three years old, because that is when depreciation is on the maximum setting.
Before I would buy a Chinese vehicle, I would want to know if it would stick around for the long haul, or become a piece of junk after 150,000 km. I'm happy to let others be the lab rats until then.
