A vehicle with salvage/rebuilt title has historically been valued at 50-60% of a "clean" title vehicle of same or similar make, model, trim level, and mileage.
Based upon my conversation with a very experienced auto body shop technician, try to stay with those vehicles that had rear damage, not front with air bag deployment. The "before" repair photos can be very helpful. If possible, take it to an auto body shop for inspection. I bought a 2008 Mazda MX5 PRHT, back in 2012. It was a salvage vehicle with slight front and mostly rear damage. It had 42,000 miles on it and it has been almost bulletproof for all these years. One suspension component had to be replaced but everything else was fine.
Check with your insurance company to see what value they would place on your possible purchase.
