Car as a present ? Lucky you haha !
If that was my car I'd definitely be hiding those 6x9s... I'd make sure it was clean (see detailing section on here) .. sort the tyres/brakes as mentioned above .. then sort the hifi out. Decent stereo (alpine would be my choice for starters but they do some budget stuff, to be avoided IMO) + decent (amped) components in the front, and then the 6x9s in the parcel shelf as they're already there... Sub OR 6x9's as they're sharing the same air in the boot. Also worth modding the cabling in the back so you can pop the parcel shelf out with some bullet connectors it haven't already.
I'm assuming you're <20 so insurance will be hilarious if you mod it. Insurance seems to be utterly hilarious at the moment anyway.
Aside from that .. enjoy it ! They're a decent handling car, albeit a bit slow in 1.2 form, but for a first car it's all you need. My 50hp 1986 micra kept me amused for the first year of my driving life. Not enough power to get in too much trouble, and cheap to run. It's all you need really as most new drivers become a statistic!
Enjoy .. but most importantly keep it between the ditches !
Edit: seen your last post .. don't go to renault for anything service related...! They know nothing (find the 'funniest thing a dealer has told you' thread) but how to rip people off.
