The problem with rebuilding salvage vehicles for a profit is that one has X dollars to spend and that's it. That leads to short cuts. Just has to.
The trick to avoiding this is knowing where to buy and how to buy. Salvage cars do not sell for a lot of money and still leaves a lot of room to do quality repairs and still make a profit.
What happens a lot of times is people with little or no experience will go and buy a car, they have no clue what that car sells for or what its worth. They will buy it for more than they should have. Once they realize they will not be able to sell it for a decent profit they will begin to save money in anyways they can. Repairing the damaged parts, using used parts, no inspections and such.
This is why its so difficult to work in this business, here we are trying to work with honesty and integrity when the majority of salvage rebuild able dealers will take shortcuts and give salvage the bad name people know it as.
Keep in mind, im not in anyway shape or form trying to represent all salvage dealers, im simply trying to say that there IS such a thing as a quality salvage vehicle that cost a lot less then the MSRP people would pay for one at the dealer.
