The time proven rule is that when buying a used Porsche you should also plan on spending another $2k within the first year.
This has proven to be accurate most of the time. It will either be for mechanical necessities or desirable upgrades but it happens every time.

As for the car, it depends on the collision and where or how extensive the damage was.
If it was superficial denting then your probably fine at that price but if the damage was more extensive, effecting alignment or fit of surrounding parts, unseen trany damage etc then pass.

My gut would say pass and look for one that was never in a collision, there are plenty out there if you are patient.
