Styling Which Seicento upgrades?

[Numptey]

I tried to sell my Seicento to buy a bigger car, but I couldn't do it, it's the only car I ever bought new. So I have decided to make it faster, better looking and add gadgets. Can anybody advise me as to what inexpensive things I can do to it to make it run smoother, slightly faster, better looking and add things like central locking, electric windows and corner better?
Oh and I am not a mechanic so be gentle with me.
