So I have 2 issues . I have a terrible wi f noise coming from the two glass sunroofs if I go over say 40 mph , is that to do eithe rhino bars fitted ? Also I have the field master , 5 seater and road tax is only £190 . Mi r is on a 2023 plate and just renewed my road tax expecting it to be £600 or do but pleased to see £190 pop up . How is this possible ?
