Long ago, when my wife drove a Taurus wagon, which came with a donut spare but had room for a full-size under the floor in the back, I tried this twice. Each time, they gave me the one with the hole in it, clearly marked! The second time, I specified which one to keep and they marked it as such, still got the wrong one! @#$&^$^#^@%^%^*!
Well, there's the problem, right there.
I have a Coates set up in my shed. I keep what I want.
