I have some words of wisdom, salvage titles can mean many things and you need to look at the vehicle to understand what it means.
When you have a 20 year old car, worth 2k tops, a company will salvage it out for the dumbest thing as the cost to repair just about anything costs more than it is worth. In that instance, I would consider spending 1 or 2k on a nice looking older truck with a salvage title.
We are looking at a 2006 45runner with a market value of between 18 and 22k depending on location and condition and it has a salvage title. This truck only has 9k miles, which tells me a couple of things. It was either so destroyed that it sat somewhere for YEARS or it has a new engine, caused from a wreck or flooding, that only has 9k miles on. The insurance company will total a car when the price to fix reaches a certain point, relative to its value. Every company has a different formula, but what that means is, what ever happened to it was bad and caused the insurance company to walk away. It ALSO means that the insurance company did not pay to have it corrected, which means that someone did it on their own... probably for cheap. Insurance companies give warrenties for their repairs, and a shop doing insurance repair work usually goes first class on the repair. They have to, bc if they don't everyone gets pissed. When I take my totaled car back and have my buddy's shop down the street repair it, I am looking for cheap as can be.
EITHER way, when I see a vehicle that is worth serious money and is titled, that tells me that something extremely bad happened to it.
Walk away. I wouldn't pay 4k for it. Unless you can find out, exactly, what happened to it; it is in my opinion, too much of a risk.
Also. 14k for a salvage title is too much.
