2019 Audi A5 STEERING,SUSPENSION,WHEELS

I was driving when the rear of my car began vibrating, then fishtailing and I lost control and hit a curb resulting in mostly forward damage. In reviewing the Preliminary Estimate from the auto-shop and insurance adjuster, there was quite a bit of damage to the Rear Suspension including a broken Trailing arm lock nut, washer, and bolt, as well as the Protector lining, lower control arm, its lock nut and the control arm mount bolt. The broken rear axle components caused me to lose control of my vehicle resulting in forward impact with a curb. My car was deemed a total loss with $28K in estimated repairs.
