Should I do it or not??
Well seeing that your expenses are on the low side (I've got 4 kids - 2 in university) then I would say go for it. I got sick and tired many years ago of the so called "streeted" cars that couldn't get out of their own way. The 400% overdriven 8-71 equipped 400 degreed cam slowboats. A toy that owes nothing to no one and can sit for periods is just what the doctor ordered to make the ultimate playtoy. But you and I and everyone else knows there is no such thing as ultimate. When you reach it the bar has been moved. And you're into heavy dollars for each mod now.
Go for it. At least you can convience yourself that this is the last mod. :P :P
