Could be impossible, but you might try finding someone who has done it before, maybe your insurance agent or adjuster could get a list of X-fire repairs and the shop that did the job. They have this info, but I don't know if they will release it to you. If they have a "Public Adjuster" - PA in your area maybe a PA could get this info. A PA is an independent Adjuster that doesnt' work for the insurance company. Used most often for Large Property Claims.

Off Topic: I used one several times for My Client's. With good results Once for a personal claim - he told me about Diminshed Value (DV). I have a 1998 Chrysler Van the got hit after I had it for only one month. My Insurance would not pay me DV, although its allowed under Florida law. He got me an appraisal after the Van was repaired cost me $85 and I got $6000. Damage to the Van was $7500 I wanted it totaled but in Fl the damage has to be 80% of value. Still have the Van.
