Another thought... just got back from my yoga class...

To get all Byron Katie on you: you CAN'T know that the accident, spending the money, and getting a new car weren't exactly the right thing to happen in your life right. I mean the accident may have been completely bad, wrong, bad to spend the money, etc.... but you CAN'T KNOW that for sure.

But if you BELIEVE that spending the money now is not a good thing and that it's your fault that you had to spend the money now... if you believe that, you feel guilty... but that belief might not be true... and in fact, could very well NOT be true.

You don't know. Why feel terribly guilty over an unknown?
