I keep a spread sheet on every car i own and all of the "extra" expenses.
I don't even have this car yet and I am at $4,898.16. But i should get about $1,000-$1,200 of that back when i sell my stock 20" wheels and tires.
I think i am pretty much done for a few months, or at least i hope i am. I got ALL the bolt on stuff and quite a bit of dress up stuff.
After driving the car a few months I will be doing a cam and springs install, but don't see me going any further than that.
