Accident damage,advice please
 

Sorry to say that the UK wet weather has claimed another victim.Aquaplaned into a barrier front and spun to the rear o/s.
Apart from the obvious bodywork,front and rear bumper, internal wing and bottom pan plastic cowlings and a rear puncture.
These parts are damaged within the o/s rear wheel arch, can someonè please give me advice on what this sheared part is and is it an inexpensive repair,and what other failed parts may have failed when this shears off?

Looks like the rear toe arm was sheared off. Generally, this is a relatively affordable ($130) and easy part to replace. The car will definitely need an alignment.

However, with this kind of serious suspension damage, you need to have the entire car and all of the suspension components fully inspected by a professional as there are likely other components that may have been damaged.

The Boxster is a unibody structured car meaning it doesn't just sit on a frame. The thing that professional body shops do is to first measure the equivalent of the "frame" (suspension attachment points) to see if there is any deformation. If there is, probably a write off and investigate selling for parts through your insurance company. We call it "totaled" over on this side of the pond.

If the "frame" is good, then it is time to look at all the suspension parts and see if they are deformed in any way. Good practice is to magnaflux the parts after a visual inspection. Safest way is just replace all from a wreck that was totaled from a other end only hit.

It isn't just the damage you can see like bumper covers, it is the stuff behind the bumper covers like shocks and other bars that absorb the shock but are only good for one hit.

How much is worth spending is a matter of how much the car was worth before the hit.

I've totaled one, know the feeling.
