Its an option thankfully. That hopefully no one will have the bad taste to select.
Would have probably looked ok with a square number plate - just looks odd with a standard oblong one.The plate is structural on the 110 apparently and a design option on the 90. I think that plates something to do with accessories like the side ladder on the 110.
Re the D5 back end, its pig ugly end of and i own one, thankfully I can't see it when driving it! I went for the full dynamic pack which i think makes it look a bit better but its by far the worst land rover design choice ever!
