Ayup

Recently bought a 1st gen Mazda 3, 1.6l Takara 5DR Hatchback.
I love it, it's such a great car, and my first car ever, before this I had a massive van, so very different.

Interested to start considering some mods. New to all this, but not a complete novice.

Got a few maintenance things to do:
Oil and filter change
Spark plugs
New tyres
Headlights are awful so would be keen to upgrade them (recommendations?)
etc

Has anybody got any good links for mods available in the UK?

Thanks in advanced.
