Both the car and the g/f are replaceable

Maybe it's just time in your life for some change. My experience in life, (my own and watching others) is that the next person you date is almost always better than the one before.
I love my SVT. It's possible to find a good used one. When they were new, they were a little expensive for all the punks, so there is surely one that was owned by a responsible person somewhere. Just make sure you talk to the previous owner BEFORE you ever buy a used vehicle (has it been wrecked, oil changed, any parts replaced, WHY did you trade it). Most people will be honest with you.
