Have a look through the 'Non-Sports in Here' thread - that'll give you a few ideas of things you can do, as well as other members project threads!
I'd HIGHLY advise you become a full paid-up memberof the club too, only costs £12/€15 and you'll make it back in no time. Gives you access to trader sections where you'll get a tasty discount as a member, access to vast collections of guides and also: The marketplace where you can buy/sell parts from members!
Do you have a Phase 1 or Phase 2? 2001 puts you right on the cusp i think - i've a 2001 Phase 1 model, if you click the 'Ph1 1.4 16V' under my name - you can see some of the things i did to my non-sport
some starters:
as above, colourcoding
nice air filter/induction kit
maybe some lowering springs/coilover kit to eliminate that hectic body-roll
1.2s are good on fuel and if just looked after with a bit of care and respect - should last you a good while! My sister's boyfriend just sold his Phase 2 1.2L for something crazy like 1.5k with over 180k on the clock, always started and ran first time!
Lastly: Welcome to the club!
