Salvage Title, How much does it devalue a car?

[James Dupree]

This is a general question but I will describe an actual set of circumstances to help base the discussion. 

Subject car: 2001 Audi S4, Tiptronic, 35,000 miles, Bright Yellow w/ Tan leather interior, book value approx $25,000 w/clean title.

Car was stolen and insurance paid off before it was recovered. It had the air bags and stereo removed and front valance damaged. No other apparent damage, I have only seen pictures of this car, as of yet. Air bags and stereo have been replaced with OE parts (used I'm sure) and the valance repaired. Car overall looks to be in good shape and is said to have no major mechanical issues. 

If I were to assume, for the sake of discussion, that the repairs done were done well and there are no other significant issues with the car. Meaning the car is average condition for 3 yrs 35K miles. What is it worth with a salvaged title? How much does the salvaged title detrack from the value?

Thoughts anyone?

Thanks

Jim
