Just for completeness...
I took a couple hour round trip drive today to look at this particular TC45D with Super Steer and 17LA FEL and 1750 hours on it.
Lets just say it didn't take long for me to hop back in my truck and head home! It was definitely one of those 40 footer units. You know, looks good from 40 feet away!
Closer inspection revealed: Tweaked ROPS (subtle, but definite, must have been on its side at some time!); Broken steering wheel tilt and telescope mechanism (no tilt lock(!), no telescope); tweaked 3rd rear SCV quick connects that rendered them unusable; cracked floor platform at both side steps (from previously mentioned roll over?); mismatched tread pattern/manufacturer rear tires (but same size, tractor had two front and left rear OEM Titan R1s); FEL had Kasco "Uni-Hitch" SSL QA, which is fine, but then it had a second SSL to New Holland pin on adapter plate to connect the original pin on bucket which was a bad thing since that put the bucket a good 8 to 10" forward of where it should have been (should have purchased a genuine SSL bucket or removed factory pin on brackets and welded on a flat SSL connector plate).
With all I could see with a visual inspection, I didn't even bother firing it up and taking a test drive.
But, hey, they "only" wanted $14,500 for the tractor...

Seemed like a reasonable kind of price for a 6 year old model with 1750 hours on it, assuming it was in good to very good condition otherwise.
Bottom line? No thank you, I'll pass on this tractor!
