I agree with dansauto. A car can be brought back from the dead. The problem is, you can often buy a good car for the same final price.
My Viper wasn't a wreck or salvage, just a high miles car that hadn't been treated like most people would treat a Viper.
It had a new engine but everything else needed fixing. Well, everything got fixed or replaced, mechanical, body and interior. It look's and runs great but I could have bought a normal Viper for what it cost me to fix up this one.
As usual, there are a bunch of guys on this board that will turn up their nose at anything other than a perfect, low miles, Zainoed, show car.
Let those guys have what they want and you get what you want.
If you can get a low price on a salvage car that has been rebuilt, if it drives ok and look's ok, and the price is low enough to be a deal. What the heck, buy it.
If it's the only way you can get into a Viper, do it. Just make sure you are paying quite a bit less than a regular car would cost.
The problem I see is that the rebuilds are not selling at much of a discount.
A salvage title is a big deal and a car that has one should be selling at a real discount.
