Unfortunately my headlights were standard halogen when i brought the car, so all ive done is upgraded the bulbs from halogens to hids and also put led side light bulbs in to match the lights. I was tempted to buy some headlights with the led strips in them they do look quite smart. But i think its a lot of money to invest for an led strip at the bottom of the headlight lol.
The Rota alloys I had were brought second hand however the condition was next to new. Paid around £350 for the set and the great news is they came with pretty new michelin tyres too! The ones I've got on now were a bit more dear as nobody likes to sell them. Paid £200 for the wheels alone, still second hand, got them refurbed for £150 and then had new tyres wrapped around them.
So really does depend if you mind having good condition used wheels or your more of a person where you want everything new.
