I was driving an Olga going about 10mph and crash into a pole due to lag and the entire car including the parts were all ruined. But earlier in the day I was able to get another Olga and I crashed into to the a wall going about 70mph and everything on the car including the car was still pristine. Also, when I left the car to go find extra parts and or another car to use, when I returned to my crashed car with all my loot in the trunk, the car de-spawned and basically just disappeared
