Iv'e had my defender 90 pick up for about a year .Used as a worktruck.I now want to venture further from home but find the noise levels un bearable.I have fitted a full Wright off road sound proofing kit but not much improvment.Any idea's guys.How does anybody do a journey of 100 miles.Dont suggest i swap it for a discovery which i understand is o'h so peacefull by comparison.
