that's a C-one 2003-2004 vitz 3door, you'll need to swap out the engine and gearbox, strip the interior and install customized body panels etc.
you are better off using the vitz for its intended purpose. city driving. fitting larger wheels and bodykits etc will result in a loss of fuel economy AND performance in most cases.
since you have just got the car i'd suggest you just drive it for a few weeks and enjoy the car and after a while when you start getting bored you can start fitting other things to it.
post pics of your ride BTW.
