depends on what it was the "salvage" is. there are only a couple of things it could be:
1) accident
2) water/flood damage
3) fire
and sometimes
4) theft/vandalism
salvaged cars do not hold much value. go to
www.kelleybluebook.com and go to used car retail and then look under "private party"...then when it says car's condition, select "rate-it." check the price of the car with salvage (towards the bottom of the list) and without. you'll see the difference.
sometimes it can be hard to resell a car with a salvage. but you really have a 50/50 chance. sometimes there are people out there only looking for those car because they do sell for less. it's a double edge sword.
good luck on the decision
