Full bulb upgrade (Headlights, interior, numberplate lights) Fan washer fitting, Interior footwell LEDS, De-badge. All of these mods are small and cheap.
If you are willing to spend a bit more consider: OEM Spoiler, Seat Skirts, Splitter, Wheel refurb/respray, lowering of the car etc
I have a 14 plate Ibiza. I wanted to add small mods when i first got it. I started by wrapping the edge of the grill in black and de-badging the ibiza off the back. I later got the rear windows tinted and a sunstrip added and then wrapped the wing mirrors in carbon and carbon vinyl door sill protectors.
I would have a look around at lowering and a spoiler but those are more expensive.
hope some of these gives you some ideas
I think 400ml should last a while thats what I'm hoping anyway![]()
