My suburban has a salvage title, because it was wrecked and the insurance totaled it. But the original owner has the option to buy the vehicle back and then he fixed the damage and able to resell the vehicle with a salvage title.
I also have a friend who bought a salvaged title escalade from new orleans after hurricane katrina hit. He got it from a dealership knowing full well that the interior had flood damage. But also got it Cheap that way.
I know a guy who owns a bodyshop and he goes to salvage auctions and buys wrecked cars, fixes them and then sells them on a regular bases.
Parts are cheap but its easier for insurance companies to total them out then to fork out the money to get them fixed. Especially with the value of car after the cash for clunkers.
So my 2cents is if you can get a straight driving salvaged titled truck in like new condition vs paying brand new sticker price then do it.
