All this depends on how bad the car is damaged. I repaired my friends 155 a while ago (missed a curve and ended up on a 1 foot wall with the rearend in the air!). Although the car looked total loss, no vital parts were hit. A few new body parts and a paint job later, the car looks like new. Even if the hit was hard enough to bend the main support beams they can just "unbend" your car (it's not a pretty sight, don't go and watch, it will cause immediate heart failure. Been there, done that)
As my fellow alfisti mentioned above, it all comes down on how good your repair shop is. Don't worry, you wouldn't believe the things they do these days!
