First, I am glad my car is too low for them to get mine, second, I am getting rid of it soon anyway.
Third, one of my countermen got a call a few months back asking about the price of an exhaust pipe cutter (kinda like an oil filter wrench but with cutters on the inside) and he told them $120 (it retails for about $20) because he had seen on the news the previous night about the converter thefts. The guy came in and bought it, he ended up talking us down to $80 for the $20 tool so we are pretty sure we know what he was going to use it for.
At least we got our cut.

But yeah it makes me sick to see everything getting stolen these days. Somebody broke into a water treatment plant here last week to steal pipes and water meters to sell them as scrap. Its just sickening.
