Which car is good to drive from Zhengzhou to go on road trip, Tibet? How much is the per capita consumption?

I just got back from Tibet. I come from Liaoning. I suggest entering Tibet from the Sichuan-Tibet line and leaving from the Qinghai-Tibet line. This can adapt to the altitude change, the car must have a four-wheel drive SUV, and the road conditions are temporarily bad. A car is about 200 thousand, but a good car is not necessarily. Linzhi and Lhasa must go. It's fun to walk and play. It is dangerous to avoid conflict with Tibetans. We each have 6000 yuan. Have fun. Have fun.
