I have a white fiesta zetec 1.0l ecoboost and want to make it look more like the zetec s. Two of the main obvious differences are the grill and the spoiler. Does anyone have any idea where I can get a zetec s/ st spoiler or any that look better to replace the almost non existent one on the standard fiesta? The grill seems easy enough to come by as I can get one on ebay for around £60.

I was also looking at getting my rims sprayed black, black mirrors and putting eyelids on, but are there any other mods anyone has done that they think are worth it? So far I've replaced the orange strip above the glovebox for a blue one which matches my footwell lights and have illuminating door sils so it looks decent at night. Any advice would be greatly appreciated.

Plenty of spoilers and grills on eBay or the Facebook Fiesta parts groups. Also Ford and wreckers. 

Side skirts, front lip and rear diffuser also make a big difference. However if you're doing that then it would work out cheaper and easier to have just bought a zetec-s in the first place. Getting body parts painted isn't cheap I'm afraid and finding second hand ones in your colour is hard to come by too.

Personally I would powder cost wheels rather than paint, it makes them last a lot longer as they're less prone to paint chips. Also if you an encounter with a curb you're only likely to damage the coating rather than the alloy. Should be able to find a place that does it for £40 a wheel (not including removing/fitting tyres).
