What is the experience of buying a second-hand Land Rover?

I just drove 2800 kilometers from 4s when I bought it, and the first insurance didn't arrive. The buckle of the coolant is broken and the antifreeze is leaking. At that time, in the mountainous area, Nongfu Spring was added to the expressway, and Land Rover China was finally called for rescue. The 4s shop in Lanzhou was repaired, so I used reinsurance to comfort myself, and it didn't cost me money. When the car reached 20 thousand kilometers, the exhaust pipe sounded abnormally, and it stopped after about 1000 kilometers. When the car reached 40 thousand kilometers, the throttle was a little wider and white smoke was emitted. I checked with 4s and it didn't work out. On several occasions, the whole road was covered with white smoke. When waiting for the red light, a driver reminded me that the car was smoking. Afraid of my spontaneous combustion. This problem was the longest until I changed an oil return pipe when it was 98 thousand kilometers long. The reason is that the old model found that the four-ring oil pipe had design defects, which was a free recall project of Land Rover Insurance Company. 4s not only didn't change, but also said that the smoke was normal and there was something wrong with the oil. When the car was at 70 thousand kilometers, the buckle cover of the second row of seat belts completely cracked. This is also a design flaw. All riders are wrapped in transparent plastic.
