The tyres are now delaminated causing different suspension height as the wheel/tyre diameters are now all different. The wheels will all be at different camber and toe as this alters when the suspension is at different compression heights.
There is no way 4 wheel allignment will show if the chassis is bent. All it will show is toe camber etc which can be adjusted to run true even when the chassis is out. Correct???
The allignment will be a mile out after bouncing off a pit lane wall not to mention any suspension components which are bent.
Fact is the only correct method of checking if the chassis is straight (which it's not as the arm is visibly bent) is to put it on a chassis jig.
If you think that car is salvageable and cost effective to repair why don't you buy it, fix it and sell it?
For the money the op will spend repairing it, give or take a little, he could buy an almost exact same car.
