I used a dolly to tow a junk '89 525i to the scrapper. Didn't think to take a picture of it until it was too late. The dolly was a beat-to-death rental; not too bad with the car on it, but made all kinds of noise when empty.

Got a whopping $166 for the 525i, sans drivetrain. Going price is $140 a ton. The engine & trans is going into my e28, when I get around to it. Stripped a bunch of other parts off it as well, but there doesn't seem to be a huge market for e34 parts.
