You could always do rallycross with your MK1. I have for a few seasons now. It's really fun and you could slowly transition your 2 into full rally prep if money is an issue. I still suggest buying your first rally car fully prepped. It will cost much less and you will probably get many spare parts in the deal. But of course the car is the least of the expense.
I wish I could've been there! A bunch of my friends from the rally community here in MN always goes down there to help out. Maybe next year we'll be able to come down too. It gets a little busy up here though helping organize 5 other rallies.
