Excuse me, what is the difference between the first generation and the second generation of Luna, which is better? (The more specific, the better)

Last year, I bought a first-generation Yuexing (Euro II standard). I guess you can only buy this now, because the second generation of Luna has been discontinued for a long time. How to evaluate this car? It's very cheap in Haojue's pedal. It belongs to a farmer's car. The running-in device runs well, not worse than Fuxing, and Yuexing is much more powerful than other cars in the same series. Within 100 meters, Fuxing and Neptune blue giant are no match for it. After 100 meters, it is basically the same. I filled my 100 km with two and a half pieces of oil. The car has a low chassis and a high seat. On the one hand, it is easy to wipe your ass. On the other hand, some girls have short legs and it is difficult to land. Nice work when I bought it, 4800 Hehe, finding a boss is much cheaper than others.
