Let's stay focussed guys!!
It's pretty clear now what's happened. The tracking has been readjusted after the accident, but rather carelessly, without bothering to check that the steering was centred. The car is perfectly safe (it's got through 2 MOTs) but the steering geometry will be slightly wrong. It will be perfectly fine in a straight line, but when you corner, the wheels will not move quite correctly in relation to each other, and this could lead to increased tyre wear, noise, and in the worst case, handling issues.
The two track rod ends both need to be rotated slightly, but in the same direction, i.e. so that both rod ends move towards the right of the car or both towards the left of the car as the case may be, so as to leave the tracking unaffected but the steering wheel centred. Any decent tyre dealer should be able to do that if you explain the situation to them, and it won't be expensive.
It's up to you whether you bother to do this. As I've said above, the car is probably perfectly safe and will drive perfectly well most of the time. The worst you might get is a bit of extra tyre wear and possibly a bit of noise. However, the fact is the car is not right, and the steering wheel is annoyingly off-centre! Please either learn to live with that or get it fixed properly by a tyre dealer. Please don't play around taking the steering wheel off, or it will end in tears!!
