While there are thousand of items on E Bay I would consider, bidding on a vehicle is not one of them, kicking tires is the only way to buy a car, you may end up with a sore toe but will still have a wallet in your back pocket.
You can buy a salvage car way below market value but at same time you must understand a salvage is a vehicle thats been written off by the insurance co... patched together declared road worthy with the title SALVAGE.
Had this been a clean title with only 6K, it would be worth about $60,000, common sence should have told you something is not right, I like to be on the consumers side but in this case I don't see how you were lied to, all the facts were disclosed in the history report.
If your boss has already agreed to the purchase, and you want an independent inspection performed,,, are you saying should this vehicle turn out to be a real lemon,,, your boss can walk away from the deal ?
On the positive side, if there is no frame damage it's possible you may have a fair deal.
