Don't feel bad hun, I've done the same thing! I took the cheap way out enough times when I first got my car that now I have to pay 2x to fix it!
Sad thing is...I paid the "right" price for my engine, and she STILL doesn't run right

I think I'd be less angry if I had paid 1/2 of what I did

You just gotta find yourself a mechanic that CARES about the quality of his work, and make hubby understand that with cars, you do indeed get what you pay for!
EDIT: Well, maybe you SHOULD sell her, and buy a newer Mustang!
