Picked the car up on Friday and can't stop driving him gave him a 2 hour clean on Saturday wash, clay bar and waxed...so all nice and shiny but I have a slight problem, whilst driving around I noticed a knocking sound coming from beneath the car on drivers side, so I checked underneath and found that there is a hard plastic cover there which goes from drivers side to passenger side and it's hanging off at my side.What is this for and should the garage repair it....Looks like it's going to need a new one what ever it is. Hope i'm explaining myself right :embarassed:
