Budgets are meant to be adjusted along the way. I should know. i started out just like you, and next thing i know it, I have the car on a rotisserie and blasting every nook and cranny. 7 years this may 28th, and it is by no means a show car, but it is solid and just like new, and i have modified a few things too meet my tastes.
I replaced the roof skin, 1 rear quarter, lowers panels on the other quarter, driver side floor, trunk floor, and dutch panel, using AMD products.
So yeah it pretty much sucks for $$$, but i would not have done it any other way. I plan on enjoying it and not worrying about how much i spent.
