I was rear ended at a red light by another driver, and had my repairs estimated at Gerber Collision to be $1,755.04. I was working through Liberty Mutual, the other driver's insurance company. The car was deemed repairable, so I put it in the shop to get fixed. 6 days later, I get a call from Liberty Mutual, saying the just talked to Gerber Collision, and they added a supplement of $3,589.44 bringing the total to an eye watering $5,344.48. This is a '96 Saturn involved in a fender bender that damaged the trunk, rear bumper, and the right and left rear fenders. So I go down to Gerber to find out what could possibly be that expensive from this minor accident. I am walked out to my car to look at damage that is under the body panels. The estimator shows me crumple damage to the underbody on the left side behind where the bumper was. The only problem is that is not where the vehicle was hit, and its clear from the photos there was no damage to that area. The other car went up over the rear bumper and into the trunk, and never struck the bumper itself, because she was on the gas when she hit me. I showed the estimator at Gerber the photos, showing CONCLUSIVELY that this damage was obviously from a previous owner who had the outer body fixed over it, and that it wasn't part of this accident. It certainly shouldn't be included in the cost to bring the vehicle back to the condition it was in prior to this recent fender bender. She had already submitted the information to the insurance company as if it was part of this collision repair, even though it clearly wasn't. Really, Ray Charles could see that it wasn't... It's that obvious. When I asked why obviously inaccurate information was sent to the insurance company,  I get the reply \"we write the damage we see.\" Now I am going through the mess of showing the insurance company that this damage was not part of this accident, all because the estimator at Gerber submitted old damage as new damage. Even with photos showing that area was absolutely free of any damage in this collision.  If you have any sense, stay away from this shop. They are far from professional, and its just a headache waiting to happen.
