The reason they put the lens on the grill was for the radar unit. Its there because they moved the transducer off the grill and placed it back towards the radiator, to avoid replacement of a high $$ part! In case of major front end damage. Based on the image I for one can’t see any real damage other than paint damage. Try a non dealer body shop. The 3500 seems a bit much for just a refinish and paint. I doubt the radar unit needs re-aiming.
