Yeah, I learned the hard way.
As you can tell, I'm no mechanic (I'm a girl) and have to rely on shops to do the smallest thing. Fortunately, I did find a great shop that I can trust, and they've done a good job getting the car running. They raised the car and showed me holes in the frame underneath. Here's a couple of pictures:
They told me if I put another $5,000 into it, they'll fix it... but that I can wait a little while to do the work.
For now, it's running and it looks gorgeous (as long as you're not looking under it!)
