To illustrate my point of ROI, recently these two CSX's were posted on ClubCobra.
The first CSX, CSX4158, is an alloy bodied replica that is currently listed at $190,000. I don't think it will sell for anywhere near $190,000, because it's a "salvage/flood" car, but $190,000-$200,000 is roughly the higher end of "ask" prices on alloy bodied CSX's. Some may ask more, some may ask less.
If you buy an alloy CSX roller for $160,000-$165,000, which may be an outdated price, add an engine, trans and detail it to the 9's, make it a true "authentic" replica, a buyer's cost will be WAY WAY over $200,000. In fact, the cost of such a car will probably approach $250,000 all in. Well, if your cost is $250,000 and your sales price is $200,000 at best, then you lose $50,000. That's not a great ROI. Negative in fact.

Now here's a fiberglass CSX, CSX 4753, recently posted here on ClubCobra. From various comments, the car needed some minor tweaks, but overall a nice complete running car, especially for the Buy It Now price of $99,XXX. Last I heard, fiberglass CSX rollers were $110,000-$115,000. That's not a good ROI, negative again, at least if that was the original buyer, which it probably wasn't.

Not all of us are Bill Gates or Mark Zuckerberg, so some of us watch our sheckels. Agree, disagree, I don't care, but that's the real world IMO. Nearly everyone here, including the OP, has a budget because we worry about the ROI when it comes time to sell.
