Need to find a shop that can check for any structural damage.

Well i pretty much need a shop that can tell me if a car has been into an accident or not. I did the car fax and everything. Nothing popped up but i did some half assed free car fax site and it said it had been an a accident that caused it to have a salvage title But the owner has a “Pass-Fit” ownership not rebuilt. I just need an honest person to let me know if it has been in an accident or not if anyone knows a reputable shop preferably a body-shop that can help me out with this it would be greatly appreciated. And as an incentive i can give a few free car fax searches for you guys. Thanks

whereabouts? KW?
