How do you value a Salvage Title car?
 

In my search for a 2007 CLK63, I came across what turned out to be a nice one with 18k miles and a salvage title. The owner went over the damage with me and it didn't seem too bad. It looked like everything was exterior skin. I know these types of accidents can add up quick because I was rear-ended in my CLK last year and if all of the damage was realized on the original inspection, my car would have been totaled and become a salvage by my insurance company. The car was repaired without issue and everything has been fine since then.

So how do you come up with a price for a car like this? Half of KBB? Is it true that dealers won't service a salvage title car? (I read that on another board) If the price is reasonable, I'd have the car inspected by both a mechanic and body shop.

Thanks for any help
