That's why you put it in a seperate account, like a savings account. My dad and I recently had this conversation, he's bought so many $500-1000 pos project vehicles that if he had just saved up and held out, he could have had a COUPLE super nice running toys (he's bought a lot of crap projects...) Those $500 trucks are going to cost you thousands each to get safe and road worthy...
I really wish I could buy this one, but with 3 classics, 2 dailys, and a work truck... I have too many now as it is. It's down in Greenwood, well, I guess "up" for you.
