While my response may have been a bit tongue in cheek it does identify what and how far you could actually go depending on how deep your pockets are.
But Id advise firstly it is a waste of money unless you get great joy from it and intend on keeping the car for a while, secondly start with a budget, based on what your plan might be, then double it, and finally have a plan.
Te plan could be as simple as wheels and lower it through to somewhat like my earlier post.
for simple things likke wheels and suspension there are plenty of shops out there, boib janes and peddars for example. for more serious mods there are more specialist shops but get on the net, especially UK and US sites for the fiesta to see what they are doing and whos products they are useing...but never forget the Australian modifiers/mechanics/suppliers are equal to any in the world so shop here first

good luck
