I'm not exceedingly jealous as I have some nice 15" wheel trims on my Vectra, which is er... 118bhp I think. Should I have wanted something on massive wheels and much improved power, I wouldn't have bought the Vectra. What I don't understand is, why buy a Discovery if you want something oozing power with 65bhp(ish) power increases and ultra low profile tyres which must hamper it's ride. Do you have intentions of lowering it?
Quite simple really, each person is entitled to be impressed with what they consider to be a good modification. In this case, I just don't get it.
