Many of us buy things that in the end turn out to have been a complete waste of money or an absolute dud.
I am loathed to admit what mine have been or are, there have been a few.
Mine, upon reflection, was likely the two wrecked lightweight Land Rovers I bought from Wainwright through PWGSC at about $500 each and paid $400 a piece to truck them back and spent money on rent to store them and finally had to unload them at scrap value
Come on, fess up

Im sure im not the only one here who has done this.
