Thoughts + Insurance Advice

Just bought this bad boy for 6000 today. Recently wrote off a 2019 cerato GT; long story short drove into a pole on the floor in the middle of the road but because it was stationary it was my fault so I lost about 10k on all costs combined. I personally think my car wasnt that fucked but repair report showed a lot of mechanical issues- 26k in repair. i feel like theyre taking my car parts cause its still so new. I am sussing out insurance for this new car now, any advice because i so dont wanna go with AAMI again.
