Recently downgraded from a BMW company car, to my own brand new Celica (premium pack). Can't get used to all the noise though - especially the creaking sunroof. Tried padding it with tissues, lubricating the side runners with silicone grease, but it keeps coming back. On a long run it drives us mad. Any suggestions?
Also the wheel arches amplify every bit of road grit thrown against them. Is it worth putting a layer of underseal on the plastic linings?
