Ala Khatib

"Driver had his ICC bumper come off at a nearby customer. These guys are great. Called Dan in service and he was nothing but GREAT help. they found the least expensive way of doing things for me. any other shop would've forced me into buying a new bumper. these guys straightened, welded, sanded, painted and re-taped it. AWESOME work guys. in Louisville frequently. 100% my go to guys when i go down there and need something. Thanks Fellas!"
