If i add a set of alloys and angel eyes to my car will it lose any value that the car might have?

i have a 54 plate 1.4 vauxhall astra, completely standard. it has the original 16" vauxhall alloys and original headlights. i fancy a set of 17" alloys and a pair of angel eye headlights. If i were to sell the car sometime in the future would i get more money for the car if i was to just leave it standard or would it not make much of a difference?
