You are right Joe, I bought a 400psi Ninja with hot solvent tank, carpet brush and all the trimmings off eBay. Drove 100 miles to pick it up and was confronted with machines and equipment that were wrecked. Told him no chance was I paying over 2k for it, in fact I did not want it at any price, I did write about it last year.
Would never part with any money until I had seen the equipment running when buying anything of value off eBay and especially weary of people who want Paypal deposits or full payment before pick up.
