Two things stick out for me here:
I had no idea it was possible to lease a used car, and it's a fucking brilliant business plan since used cars don't depreciate very much. I'd be interested to see the terms of the deal though, since leases are based upon a predetermined depreciation amount set by lenders. I wonder if they used KBB.com to set the residual?
The second thing is that I wouldn't pay the impound fees either. $2,000 won't break me, but I'm not letting that money out of my pocket to go to the govt, because I know that once I've paid it, I'm never getting it back even if it was not my fault. Props to her for sticking it to the man.
