I think itís safe to say the unit was available at the time it was listed 19 hours ago. However, itís possible it had already been listed elsewhere or parked locally with a sale sign. Itís also possible someone here local to the seller jumped on it yesterday evening.
These things sell fast, and T4500ís are uncommon and desirable. Frustrating, but probably not a conspiracy to tease wannabe buyers.
I just hope the buyer doesnít think it really weighs 900#!
