hiya matey, cars looking good so far!
as said, what about some new bulbs?! they're pretty cheap, and a very effective mod as removing the 'fried egg' look from the front lights is a worthy mod!
before:
after:
also, what about replacing the headlight bulbs for xenon effect ones? all they do is give a whiter, brighter light, so the road is a bit more visable than when you have the standard 'yellow' look bulbs which look awful imo.
depending on how much you have to spend matey, there is an interior lighting kit available (pm me for details)
then you can move onto improving the paintwork... some nice polish/wax/sealant will make it stand out more, make it look great, and look after the paintwork for you as a bonus!!
then you could paint the callipers, i used hammerite, about a fiver from b&q, a couple of coats and bobs your mothers brothers!!!
depends how far you want to go matey, but callipers and changing the front indicator bulbs and headlight bulbs is a worthy cheap mod imo... then you could also replace the read brake lights and tail lights for l.e.d. units too!
new number plates??
so, there is a few mods for you to be getting on with!
