alot of great points in this thread but I don't think its fair to include general maintenance. Every vehicle needs maintenance and repairs. I've learned alot from my restoration and some parts are better to invest in new and other are better to shop around for used.
Electrical parts are a great example, I will never buy NOS electrical stuff ever again. Also, no more NOS gaskets and finally, I would have all my wheel cylinders re-sleeved with stainless steel from the beginning, other wise I really don't see any excessive maintenance cost unless something catastrophic happens.
Remember Grease is Cheap, Parts aren't!
